Crochet Sunflower Blanket: A Beautiful Step-by-Step Granny Square Pattern

Bring a little sunshine into your home with a handmade crochet sunflower blanket. Each square features a warm brown center, golden yellow petals, and a coordinating background that frames the flower beautifully. Joined together, the motifs create a cheerful blanket that looks lovely on a sofa, across a bed, or in a cozy reading corner.

This beginner-friendly project is also a thoughtful handmade gift. Choose cream, beige, or soft green for the background, or use several complementary shades to create your own sunflower-inspired design.

1. Project Overview

Project name: Crochet Sunflower Blanket
Skill level: Advanced beginner
Construction: Individual sunflower squares joined into a rectangle
Recommended yarn: Worsted-weight yarn, preferably a washable acrylic or acrylic blend
Recommended hook: 5 mm (US H-8), adjusted to match gauge
Estimated finished size: Approximately 40 by 50 inches
Estimated motif size: Approximately 10 by 10 inches per square
Estimated motif count: 20 squares, arranged 4 across and 5 down
Estimated completion time: 20–35 hours
Estimated yarn requirement: Approximately 1,800–2,400 yards total, depending on yarn, tension, joining, and border
Main joining method: Single crochet join
Border: Two rounds of single crochet in a coordinating color

These are estimates, not guaranteed measurements. Your finished blanket size will depend on the size of each motif, the thickness of the joining seams, and the width of the border.

The pattern uses a brown circular center, eight yellow petals, and a cream square-forming round. The design is intended to produce a recognizable flower with four clear corners and straight edges for joining.

2. Materials and Supplies

Gather the following supplies:

Brown or golden-brown yarn for the center
Yellow or golden yarn for the petals
Cream, beige, or another coordinating color for the square background
Optional green yarn for decorative accents
5 mm crochet hook, or the size needed to achieve gauge
Scissors
Yarn needle
Measuring tape
Optional stitch markers
Optional blocking mats and rust-resistant pins, suitable for your yarn

Choosing yarn

A washable acrylic yarn or acrylic blend is a practical option for a blanket because it is often easy to care for. Cotton blends can also work, though they may produce a different weight and drape. Check the yarn label before choosing your care method.

Use a similar yarn weight for all three main colors. Differences in thickness can make the petals uneven or cause the squares to vary in size.

Hook size and tension matter, too. A smaller hook generally creates a denser fabric, while a larger hook creates a looser fabric. Very tight stitches can make the square curl, while loose stitches may produce large gaps between petals.

Make one complete sample square before crocheting all 20 motifs.

3. US Crochet Abbreviations and Techniques

This pattern uses standard US crochet terminology.

ch: Chain
sl st: Slip stitch
sc: Single crochet
hdc: Half double crochet
dc: Double crochet
tr: Treble crochet
st: Stitch
sts: Stitches
sp: Space
ch-sp: Chain space
rep: Repeat
rnd: Round
sk: Skip
FO: Fasten off

Basic techniques

Slip knot and chain: Make a slip knot, place it on the hook, then yarn over and pull through the loop to create each chain.

Single crochet: Insert the hook into the stitch, yarn over and pull up a loop, then yarn over and pull through both loops.

Half double crochet: Yarn over, insert the hook into the stitch, yarn over and pull up a loop, then yarn over and pull through all three loops.

Double crochet: Yarn over, insert the hook into the stitch, yarn over and pull up a loop, yarn over and pull through two loops, then yarn over and pull through the remaining two loops.

Treble crochet: Yarn over twice, insert the hook into the stitch, yarn over and pull up a loop, then work through two loops at a time three times.

Slip stitch: Insert the hook into the indicated stitch, yarn over, and pull through both the stitch and the loop on the hook.

Understanding stitches and spaces

A stitch is the completed crochet stitch itself. A chain space is the opening created by chain stitches, such as the gap beneath a chain-2 sequence. When the pattern says to work into a chain space, insert the hook into the opening rather than into a chain’s top loops.

Joining slip stitches do not count as regular stitches unless specifically stated. In this pattern, beginning chains are described in each round, and stitch totals refer to completed stitches rather than joining slip stitches.

4. Gauge and Finished Dimensions

For this pattern, use the following as an initial target:

Finished motif: Approximately 6 by 6 inches
Blanket layout: 4 motifs across and 5 motifs down
Estimated blanket before border: Approximately 24 by 30 inches
Estimated finished blanket with border: Approximately 26 by 32 inches

The actual size depends on your tension, yarn, hook, joining seams, and border.

How to measure a sunflower square

Measure from the outer edge of one side to the opposite outer edge, then measure the other direction. Each completed square should be approximately the same size before joining.

Make a sample motif first

Crochet one complete square using the instructions below. Lay it flat without stretching it and measure it.

If the square is smaller than expected, try a slightly larger hook. If it is too large, try a smaller hook. Use the same hook and tension for the remaining motifs once you are happy with the sample.

Consistent motif size is important because squares that differ noticeably in size can make the joined blanket pucker or have uneven edges.

5. Understanding the Sunflower Motif

Each square is made in four stages:

Brown center: A small circle worked in single crochet.
Brown preparation round: An increase round creates 16 stitches, giving enough positions for eight evenly spaced petals and the square background.
Yellow petals: Eight small shells made from double crochet stitches form the flower.
Background square: The background yarn is worked into the stitches left between the petals. Four corner groups shape the flower into a square, and a final single crochet round gives the edges a neat finish.

The petals sit over the center, while the background stitches form four clear corners and four joinable sides. This creates an integrated sunflower granny square rather than a flower simply attached to the surface of a separate square.

6. Complete Round-by-Round Sunflower Motif Pattern

Use brown yarn for Rounds 1 and 2, yellow for Round 3, and cream or another background color for Rounds 4 and 5.

Round 1: Brown center

Make a magic ring. If you prefer not to use a magic ring, chain 2 and work into the second chain from the hook.
Chain 1. This chain does not count as a stitch.
Work 8 single crochet stitches into the ring.
Pull the ring closed if using a magic ring.
Join with a slip stitch to the first single crochet.

Stitch count: 8 single crochet stitches.

This creates the small, circular center of the sunflower.

Round 2: Increase the brown center

Chain 1. It does not count as a stitch.
Work 2 single crochet stitches into each stitch around.
Join with a slip stitch to the first single crochet.

You will have 16 single crochet stitches.

Stitch count: 16 single crochet stitches.

Fasten off the brown yarn, leaving a tail to weave in. This round provides eight petal positions and eight spaces between those positions.

Round 3: Yellow sunflower petals

Attach yellow yarn to the first stitch of Round 2.

Each petal is made in one stitch using the following sequence:

Slip stitch into the stitch.
Chain 1.
Work 3 double crochet stitches into the same stitch.
Chain 1.
Slip stitch into the same stitch again.

This forms one rounded petal.

Repeat the petal sequence in every other stitch around the center. Skip one stitch between petals, then make the next petal in the following stitch. Continue until you have made 8 petals.

Join with a slip stitch to the first joining point, taking care not to pull the petals tightly together.

Petal count: 8.

Fasten off yellow yarn. Weave in the ends carefully, keeping the petals evenly spaced. The eight skipped stitches between the petals remain available for the background round.

Round 4: Turn the flower into a square

Attach the background yarn to one of the unworked brown stitches between two petals. These are the eight stitches skipped during the petal round.

This round uses four corner groups and four side groups. The corner groups are placed in alternating skipped stitches, with a side group between each pair of corners.

Corner group: Work 3 double crochet stitches, chain 2, then 3 double crochet stitches into the same skipped brown stitch.

Side group: Work 3 double crochet stitches into the next skipped brown stitch.

Work around the motif in this sequence:

Make a corner group in the first selected skipped stitch.
Make a side group in the next skipped stitch.
Make a corner group in the next skipped stitch.
Make a side group in the next skipped stitch.
Continue alternating corner and side groups until you have made four corner groups and four side groups.
Join with a slip stitch to the first double crochet of the round.

The corner groups should be positioned at four roughly equal points around the flower. The chain-2 spaces form the four square corners.

Round count: 4 corner groups and 4 side groups.

If the flower does not lie flat, check that the background stitches are placed into the eight skipped brown stitches, not into the yellow petals. Keep the corner chain spaces loose enough to allow the square to spread.

Round 5: Finish the square edge

Continue with the background color.

Chain 1. This chain does not count as a stitch.
Work one single crochet into each double crochet stitch around.
At each corner chain-2 space, work 2 single crochet stitches, chain 2, and 2 single crochet stitches into the space.
Continue around all four sides.
Join with a slip stitch to the first single crochet.

Do not work into the joining slip stitch as though it were a regular stitch.

Fasten off and weave in the remaining ends.

This final round creates a more defined edge and keeps the corners easy to identify when joining squares.

Check the completed motif

Each sunflower square should have:

One brown center
Eight yellow petals
Four clear corner chain spaces
Four straight sides
A finished background edge

Lay the square flat. It should be reasonably square without curling or ruffling excessively.

7. Changing Colors Neatly

The main color sequence is brown, yellow, then cream or another background shade.

To change colors:

Finish the final stitch of the current round.
Cut the yarn, leaving a tail long enough to weave in.
Attach the new color with a slip knot or by completing the joining slip stitch with the new yarn.
Begin the next round in the specified stitch or space.
Weave in each yarn tail securely on the wrong side of the motif.

Avoid pulling the yarn tails too tightly, as this can make the center pucker. For a neat finish, weave each tail through several stitches and change direction before trimming the excess.

8. Making the Full Set of Motifs

Make 20 sunflower squares for the example blanket.

To keep the squares consistent:

Complete one sample motif and measure it before making the remaining squares.
Use the same hook and yarn weight for every motif.
Count the eight petals on each square.
Check that each square has four corners and four joinable sides.
Weave in ends as you finish each motif, rather than waiting until the entire blanket is assembled.
Lay the completed squares together periodically to compare their dimensions.

If you want a coordinated look, use the same brown center and yellow petals for all 20 squares. You can vary the background color in a planned pattern, but keep the background yarn weight consistent.

9. Arranging the Sunflower Squares

Arrange the motifs in a rectangle with 4 squares across and 5 squares down.

A simple layout uses the same background color for every square. This creates a consistent frame around each sunflower.

Before joining, place all the squares on a flat surface. Turn each motif so its petals face the same direction, then check that the corners line up.

If you use multiple background colors, distribute them evenly rather than placing all the same color in one corner. Take a photo of your chosen layout or mark the order of the squares so you can maintain it while joining.

The estimated dimensions for this layout are approximately 24 by 30 inches before the border if each motif measures about 6 inches square. The seams and outer border increase the finished dimensions slightly.

10. Joining the Sunflower Squares

This tutorial uses a single crochet join. It creates a visible, slightly raised seam that complements the textured sunflower motifs.

Step 1: Position two squares

Place two squares next to each other with their right sides facing upward.
Align the corresponding edges and corner spaces.
Check that the motifs are oriented correctly.

Step 2: Start the join

Use the background yarn or another coordinating color.
Insert the hook through the corresponding edge stitches of both squares.
Attach the yarn and chain 1.
Work one single crochet through the paired edge stitches.

Step 3: Continue along the edge

Insert the hook through the next corresponding stitch on both squares.
Make one single crochet.
Continue working through matching stitches along the edge.
Keep the tension even so the squares remain flat.
At the corner, make sure the corner spaces of both squares are aligned before continuing.

Use the same joining approach for each shared edge. Avoid pulling the joining yarn too tightly, which can cause the blanket to pucker.

Step 4: Join the rows

Join the squares into horizontal rows first. Then place the rows together and single crochet along the shared edges to connect them.

At intersections where four squares meet, keep the seams flat and avoid adding extra stitches that create bulky knots. Secure the yarn ends and weave them in on the wrong side.

Alternative joining method

You can sew the squares together with a yarn needle for a flatter, less raised seam. If you choose this method, use it consistently throughout the blanket.

11. Adding the Blanket Border

A two-round single crochet border gives the blanket a neat, finished edge.

Use the background color for a subtle frame or a contrasting shade for a bolder look.

Border Round 1

Attach the yarn at an outer corner of the joined blanket.
Chain 1. This chain does not count as a stitch.
Work single crochet stitches evenly along the outer edge.
Along edges formed by row ends, distribute the stitches evenly rather than forcing one stitch into every row end.
At each outer corner, work 1 single crochet, chain 2, and 1 single crochet into the corner point.
Continue around all four sides.
Join with a slip stitch to the first single crochet.

Border Round 2

Chain 1.
Work one single crochet into each stitch around.
In each corner chain-2 space, work 1 single crochet, chain 2, and 1 single crochet.
Continue around the blanket.
Join with a slip stitch to the first single crochet.
Fasten off and weave in the ends.

Keeping the border flat

If the border pulls inward, undo the affected section and add stitches more evenly along the outer edge. If it ripples, reduce the number of stitches slightly. The goal is a border that lies flat without stretching the squares.

12. Finishing and Blocking

After joining the squares and completing the border, inspect the blanket carefully.

Weave in any remaining yarn tails.
Check that the seams are secure and that there are no open gaps between motifs.
Measure the width and length.
Check that the outer edges are straight and the corners lie flat.

Blocking may help even out the motifs and improve the overall shape. Follow the care instructions for your yarn. Some fibers can be gently shaped while damp, while others need a different method. Avoid excessive stretching or high heat if the yarn may be damaged.

If you block individual squares before joining, allow them to dry completely and make sure they are all the same size. If you block the finished blanket, shape it gently without pulling the seams out of alignment.

14. Customization Ideas

Change the sunflower colors

Use deep brown centers with golden yellow petals for a traditional look. Pale yellow petals and cream backgrounds create a softer style, while mustard yellow and beige can give the blanket a warm, earthy appearance.

Try a different background color

Cream and beige make the flowers stand out. Soft green can suggest foliage, while charcoal or navy creates stronger contrast.

Add green accents

Green yarn can be used for a decorative border or for small leaf motifs added between flowers. If you add separate leaves, secure them firmly and keep the design consistent across the blanket.

Make a larger blanket

Increase the number of motifs across, down, or both. For example, adding one column increases the width by approximately one motif’s width, plus any additional seam allowance. Adding one row increases the length in the same way.

Make a smaller lap blanket

Use fewer motifs in a smaller rectangular arrangement. Keep the number of squares consistent with the layout you choose, and adjust your yarn estimate accordingly.

Change the border

A contrasting border can frame the blanket, while a matching background color creates a quieter finish. If you try a textured border, check that it lies flat and does not distort the outer edges.

Adjust yarn weight and hook size

Thicker yarn and a larger hook generally produce larger motifs and a heavier blanket. Finer yarn and a smaller hook produce smaller motifs. Always make a sample square before estimating the total yarn or changing the motif count.

15. Troubleshooting

The center curls or becomes wavy

Likely cause: The stitches are too tight or the increases are uneven.

Solution: Check that Round 2 has exactly 16 single crochet stitches. Try a different hook size if the center remains distorted.

The petals are uneven

Likely cause: The petal stitches are not being worked into alternating stitches consistently.

Solution: Count eight petals and check that each petal uses the same sequence: slip stitch, chain 1, 3 double crochet stitches, chain 1, and slip stitch.

The petals look too short or bulky

Likely cause: Your yarn thickness, tension, or hook size differs from the example.

Solution: Make a sample petal round with the same yarn and hook you intend to use. Adjust the hook if necessary, and use the same size for every motif.

The square does not have four clear corners

Likely cause: The background round has been worked into the wrong stitches or the corner groups are not spaced evenly.

Solution: Locate the eight skipped brown stitches behind the petals. Place corner groups in alternating skipped stitches and side groups in the stitches between them.

The motifs are different sizes

Likely cause: The tension, yarn, or hook varies between squares.

Solution: Use the same hook and yarn weight throughout. Measure each completed motif before joining, and gently shape any minor differences if the yarn allows.

The square-forming round creates gaps

Likely cause: The background stitches are too loose or the corner spaces are too large.

Solution: Keep the tension consistent and make the corner chain-2 spaces the same size in every motif. The flower petals should remain visible without leaving large openings between the square edges.

The joined blanket looks puckered

Likely cause: The joining yarn is too tight or the motifs are not the same size.

Solution: Undo the affected seam and rejoin with more even tension. Align the corners and edges before working each seam.

Four-motif intersections are bulky

Likely cause: Several seams have been tightened or knotted at the same point.

Solution: Keep the joins even, avoid bulky knots, and weave in yarn ends separately on the wrong side.

The border pulls inward or flares outward

Likely cause: Too few or too many stitches have been worked along the outer edges.

Solution: Undo the affected section and redistribute the single crochet stitches. Keep the chain-2 corner spaces consistent.

You run short of yarn

Likely cause: Your motifs are larger or denser than expected, or the joining and border use more yarn than anticipated.

Solution: Measure the yarn used for a sample motif and use that amount to improve your estimate before making the full set. If possible, purchase extra yarn from the same dye lot.

16. Care and Maintenance

Care for your sunflower blanket according to the yarn label.

Washing: Check whether your yarn is machine washable or requires hand washing. Use a suitable detergent and avoid harsh treatments unless the label permits them.
Drying: Follow the recommended drying method. Lay the blanket flat if necessary to help preserve its shape.
Storage: Store the blanket clean and completely dry in a dry, well-ventilated place.
Maintenance: Inspect the joins and border occasionally. Repair loose stitches before they unravel further.

If the blanket combines different fibers, follow the most delicate care requirements among them. Avoid high heat or aggressive stretching that could damage the yarn or distort the squares.

17. Frequently Asked Questions

Is a sunflower blanket suitable for beginners?

Yes, especially for crocheters who already know single crochet, double crochet, and slip stitches. The flower and square-forming rounds require careful stitch placement, so making one sample motif first is helpful.

How many sunflower squares are needed?

This example uses 20 squares arranged 4 across and 5 down. A larger blanket can use more motifs, while a smaller lap blanket can use fewer.

What yarn works best for a crochet blanket?

Washable acrylic or an acrylic blend is a practical choice. Cotton blends are another option. Choose a yarn that feels comfortable and follow its care instructions.

How do I keep the petals symmetrical?

Use the same stitch sequence for all eight petals and place them in alternating stitches around the center. Count the petals before beginning the background round.

How do I turn the flower into a square?

Work the background round into the eight skipped brown stitches behind the petals. Alternate four corner groups of 3 double crochet, chain 2, 3 double crochet with four side groups of 3 double crochet. Finish with the single crochet square-edge round.

What is the easiest way to join sunflower squares?

A single crochet join is straightforward and creates a visible seam. Align the corresponding edges first, then work evenly through the edge stitches of both squares.

Can I make the blanket larger?

Yes. Add rows or columns of motifs, keeping the arrangement rectangular. Each additional row or column increases the overall dimensions by approximately one motif’s size, plus the effect of joining seams.

How can I keep every motif the same size?

Use the same yarn weight, hook, and stitch tension. Measure each square before joining and gently shape it if the yarn permits. A sample motif helps you establish a consistent target.

How much yarn will I need?

The total depends on the yarn, motif size, joining method, and border. For the most reliable estimate, crochet one complete motif, record the amount of yarn it uses, and estimate the remaining motifs from that sample. Allow extra yarn for joining and the border.

Conclusion

A crochet sunflower blanket is a cheerful way to combine floral color, textured petals, and classic granny-square construction. Take your time with the sample motif, keep the petals consistent, and join the squares carefully for a neat finish. With coordinated colors and a simple border, you can create a personalized blanket that brings a little sunshine to any room.
