Baby Crochet Swaddle Blanket: A Step-by-Step Crochet Pattern

A handmade crochet baby blanket is a thoughtful gift for a baby shower, a cozy nursery accessory, or a treasured keepsake. With a soft texture, a simple stitch pattern, and your choice of colors, you can create a lightweight blanket that is both attractive and customizable.

This beginner-friendly pattern uses half double crochet stitches worked in rows, followed by a neat single crochet border. The result is a flexible rectangular blanket with consistent edges. The finished size and drape depend on your yarn, hook size, stitch tension, and the way you work the border.

Important: This is a handmade baby blanket inspired by the traditional shape of a swaddle blanket. It is not a certified swaddling product or a safe-sleep accessory. A loose blanket should not be used as bedding in an infant’s sleep space, and you should not tightly wrap or swaddle a baby in a crocheted blanket unless the product and its use are appropriate under current professional guidance.

1. Project Overview

Skill level: Beginner
Project type: Baby crochet blanket
Construction method: Worked in rows from a foundation chain
Crochet terminology: US terms
Approximate finished dimensions: 30 by 30 inches (76 by 76 cm), including the border
Approximate completion time: 8–14 hours
Main techniques: Foundation chain, half double crochet, turning chains, single crochet edging, color changes, and weaving in ends

These measurements and the completion time are estimates. Your results will vary with yarn weight, hook size, tension, and experience.

2. Materials and Tools

Approximately 700–900 yards of soft, washable medium-weight yarn suitable for blankets
A crochet hook appropriate for the yarn, often around 5 mm
Scissors
Tapestry needle for weaving in ends
Measuring tape
Optional stitch markers for identifying the first and last stitches

Choose a smooth yarn that feels comfortable and produces a flexible fabric. Smooth yarn also makes it easier to see your stitches and identify the last stitch in each row. Check the yarn label for washing and drying instructions before beginning.

Cotton, acrylic, and suitable blends may all be options, depending on the desired texture and care requirements. No yarn can be assumed to be suitable for every baby or every use.

Understanding the stitches

Chain (ch): Yarn over and pull through the loop on your hook.
Single crochet (sc): Insert the hook into the stitch, yarn over and pull up a loop, then yarn over and pull through both loops.
Half double crochet (hdc): Yarn over, insert the hook into the stitch, yarn over and pull up a loop, then yarn over and pull through all three loops.
Slip stitch (sl st): Insert the hook into the stitch, yarn over, and pull through both the stitch and the loop on your hook.
Skip (sk): Leave the specified stitch unworked.
Fasten off (FO): Cut the yarn, leaving a tail, and pull the tail through the final loop to secure it.

4. Before You Begin

Start with a slip knot and a foundation chain. Try to keep the chain flexible rather than pulling each loop tightly. A tight foundation chain can make the lower edge narrower than the rest of the blanket.

This pattern uses half double crochet stitches for the main fabric. At the end of each row, ch 1 and turn. The turning chain does not count as a stitch. Work the first hdc into the first actual stitch of the previous row.

Count the stitches at the end of every row. If you consistently lose stitches at the edges, place a marker in the first and last stitch of a row to make them easier to identify.

5. Gauge and Finished Dimensions

Gauge describes the number of stitches and rows that fit into a measured section of fabric. It helps you estimate the finished size of the blanket and determine whether your hook and yarn are working well together.

Make a gauge swatch

Ch 22.
Hdc in the third ch from the hook and in every remaining chain.
Ch 1 and turn.
Hdc across the row, then repeat the same row until you have a square swatch.
Lay the swatch flat without stretching it and measure the center.

An illustrative gauge is approximately 14 hdc stitches and 10 rows over 4 inches (10 cm). This is only an estimate; your actual gauge may differ.

If your fabric feels stiff or is smaller than expected, try a larger hook.
If the fabric is too loose or much larger than expected, try a smaller hook.
If the swatch feels comfortable and has a consistent texture, you can continue with your chosen hook.

For the sample blanket, aim for an approximate finished size of 30 by 30 inches (76 by 76 cm), including the border. The foundation chain determines most of the width, while the number of rows determines most of the length.

6. Choose the Main Stitch Pattern

Half double crochet is a useful stitch for a beginner blanket because it creates fabric more quickly than single crochet while remaining relatively dense and flexible.

The pattern has three advantages:

Texture: The stitches create a simple, softly textured surface.
Drape: The fabric can bend and fold comfortably when made with suitable yarn and hook size.
Ease of learning: Each row uses the same stitch, making it easier to track progress.

The pattern repeats across the entire row. There are no skipped stitches or increases in the main fabric, so the stitch count should stay the same from row to row.

The turning chain is not counted as a stitch. This rule applies throughout the blanket pattern.

7. Step-by-Step Baby Crochet Blanket Pattern

Step 1: Make the foundation chain

For the sample blanket, ch 101.

This chain count is designed to create 99 hdc stitches in the first row, using the illustrative gauge above. The turning chain is added separately at the beginning of each later row.

Keep the chain loose enough that the lower edge can stretch naturally. If the chain feels much tighter than your normal stitches, remake it using a larger hook just for the foundation chain, if needed.

Step 2: Work the first row

Yarn over.
Insert the hook into the third chain from the hook.
Work 1 hdc.
Continue working 1 hdc into each remaining chain.
Count your stitches before continuing.

You should have 99 hdc stitches at the end of Row 1. The two skipped chains do not count as stitches.

Look closely at the final chain to make sure you have not missed it. Missing the last stitch is a common reason blankets become narrower as they grow.

Step 3: Work the main blanket rows

Row 2: Ch 1 and turn. Work 1 hdc in the first stitch and in every stitch across. You should have 99 hdc.

Rows 3 onward: Repeat Row 2, keeping 99 hdc in every row.

Continue until the main fabric measures approximately 28–28.5 inches long (71–72 cm), or until the length is appropriate for your gauge. At the illustrative gauge of 10 rows per 4 inches, this will be roughly 70–72 rows, including the first row.

This is an estimate, not a fixed requirement. Measure your blanket as it grows, because the actual number of rows needed depends on your row height and tension.

Step 4: Add optional color stripes

The main pattern is a single-color blanket, but stripes are an easy way to personalize it.

To change colors at the end of a row:

Work the final hdc until three loops remain on the hook.
Yarn over with the new color and pull through all three loops.
Ch 1 with the new color and turn.
Continue working hdc across, keeping the same 99-stitch count.

If you prefer not to carry yarn along the edge, cut the old color and weave in the ends later. Avoid leaving long loose loops or unsecured strands.

Color changes do not affect the stitch count. Keep the same number of stitches in every row, regardless of the color arrangement.

Step 5: Check the blanket’s shape

Lay the blanket flat on a clean surface and measure its width and length.

Check that:

Both side edges are reasonably straight.
The foundation edge is not noticeably tighter than the top.
Each row contains 99 hdc.
The fabric is not pulling inward or flaring outward.
The length is close to the planned measurement.

If the blanket narrows, check that you are working into the first and last stitches of each row. If it widens, you may be accidentally working into the turning chain. Remember that the turning chain does not count as a stitch in this pattern.

Step 6: Crochet the finishing border

The border uses single crochet for a clean, simple edge.

Border Round 1:

With the right side facing you, join yarn at one corner with a sl st.
Ch 1. This does not count as a stitch.
Along the top edge, work 1 sc into each hdc stitch.
At the corner, work 3 sc into the same corner stitch.
Along the side edge, work sc evenly into the row ends. Begin with approximately 1 sc per row, adjusting as needed so the edge lies flat.
At the next corner, work 3 sc into the corner.
Work 1 sc into each stitch along the bottom foundation edge. Place stitches evenly into the available chain loops.
At the next corner, work 3 sc into the corner.
Work sc evenly along the remaining side edge.
At the final corner, work 3 sc into the corner area.
Join with a sl st to the first sc.

Check the corners: Each corner should have 3 sc worked into its corner location. This creates enough extra fabric for the border to turn smoothly around the corner.

The number of sc along the side edges may vary with the actual row height. If the edge pulls inward, work a few more sc along the side. If it waves, reduce the number slightly and redistribute the stitches evenly.

If you want a more substantial border, work a second round of sc, placing 1 sc in each border stitch and 3 sc in the middle stitch of each corner group. This second round is optional.

Step 7: Fasten off and weave in ends

After completing the border:

Join the last stitch to the first with a sl st, if you have not already done so.
Cut the yarn, leaving a tail of about 6 inches.
Pull the tail through the loop on your hook to secure it.
Thread the tail onto a tapestry needle.
Weave it through several stitches on the wrong side, changing direction once to help secure it.
Trim the excess yarn without cutting the crochet fabric.

Secure any color-change ends in the same way. Inspect the entire blanket for loose strands, gaps, or stitches that may unravel.

8. Complete Written Pattern Summary

Yarn: Soft, washable medium-weight yarn; approximately 700–900 yards as an estimate.
Hook: Approximately 5 mm, adjusted to your yarn and gauge.
Foundation chain: Ch 101.
Row 1: Hdc in the third ch from the hook and in each remaining chain. (99 hdc)
Row 2: Ch 1, turn, hdc in each stitch across. (99 hdc)
Main rows: Repeat Row 2, keeping 99 hdc in each row.
Length: Stop when the main fabric measures approximately 28–28.5 inches (71–72 cm).
Border Round 1: Sc across the top, work 3 sc in each corner, sc evenly down the side, sc across the bottom, and sc evenly up the other side. Join with a sl st.
Optional border Round 2: Sc in each stitch, working 3 sc into the middle stitch of each corner group.
Finish: FO, weave in all ends securely, and inspect the fabric.

The finished blanket is approximately 30 by 30 inches (76 by 76 cm), including the border, depending on your gauge and border tension.

9. Stitch Count and Measurement Verification

Use these checks while working:

The foundation chain has 101 chains.
Row 1 has 99 hdc because the first two chains are skipped.
Every later main row has 99 hdc.
The turning chain is not counted as a stitch.
The main fabric is approximately 28–28.5 inches long before adding the border.
The border adds a small amount of width and length, depending on stitch placement.
Each corner has 3 sc in its corner location.
Color changes do not change the number of stitches.

If your gauge differs from the estimate, use the actual measurements of your work rather than relying on a fixed row count. A consistent stitch count is the best way to keep the blanket rectangular.

10. Sizing and Customization

Make the blanket wider or narrower

Adjust the foundation chain to change the width. For this pattern, the first row contains two fewer stitches than the number of chains in the foundation chain. For example, if you add 10 chains, the first row will have 10 additional hdc stitches.

For a different width, make a gauge swatch and estimate how many stitches you need across the desired measurement. Always check the actual width after the first few rows.

Make the blanket longer or shorter

Add rows for a longer blanket or stop sooner for a shorter one. Measure the fabric periodically rather than relying entirely on the number of rows, since row height varies between crocheters.

Try different colors

Use one color for a classic look, alternate two colors for stripes, or choose a neutral palette to match a nursery. If you use stripes, plan the color sequence in advance so you can manage the yarn ends neatly.

Try a different stitch pattern

You can use another beginner-friendly stitch pattern, but it may change the fabric’s density, drape, and width. Make a gauge swatch with the new stitch pattern before starting. You may need a different foundation chain and row count.

Change yarn weight and hook size

A different yarn weight can change the blanket’s size and feel considerably. Choose a hook that produces a comfortable fabric, then make a swatch to check your gauge. Do not assume the same chain count will produce the same dimensions with a different yarn.

11. Washing and Care

Follow the yarn label’s instructions for washing and drying.

Wash the blanket using the method recommended for the selected yarn.
Avoid excessive agitation if the yarn is prone to stretching or pilling.
Reshape the blanket gently after washing, if appropriate for the fiber.
Allow it to dry completely before storing.
Store it in a clean, dry place.
Inspect it periodically for loose yarn ends, damaged stitches, or unraveling fabric.

Do not use a washing or drying method that conflicts with the yarn’s care instructions. If you are making the blanket as a gift, consider including the yarn’s care information.

12. Baby Blanket Safety Considerations

This pattern creates a handmade blanket, not a certified swaddling product or a safe-sleep accessory.

Do not use a loose blanket as bedding in an infant’s sleep space. Follow current safe-sleep guidance when preparing a baby’s sleeping area.
Do not tightly wrap or swaddle an infant in this crocheted blanket unless the product and its intended use are appropriate under current professional guidance.
Avoid buttons, beads, detachable decorations, and other small components.
Secure all yarn ends and inspect the fabric for large gaps, damaged stitches, loose strands, or unraveling.
Follow the care instructions for the yarn and inspect the blanket regularly for wear.
If you are unsure which products are appropriate for an infant, consult a qualified healthcare professional and follow current safe-sleep recommendations.

A dense stitch pattern and soft yarn do not make a loose blanket appropriate for infant sleep. Use the finished blanket only in ways suitable for its design and the child’s age and circumstances.

13. Troubleshooting

Problem	Likely cause	Practical correction
The foundation chain is too tight	The chain tension is tighter than the row tension	Restart with a looser chain or use a larger hook for the foundation chain.
The blanket becomes narrower as rows progress	Stitches are being missed at the beginning or end of rows	Count each row and check that you work into the first and last actual stitches.
The sides are uneven	Stitch counts vary or tension changes	Keep 99 hdc in every main row and maintain consistent tension.
The fabric curls or feels stiff	The hook is too small or the yarn is too rigid for the stitch pattern	Try a larger hook or a softer suitable yarn, then make a new gauge swatch.
The blanket is wider or narrower than expected	Your stitch gauge differs from the estimate	Measure the actual fabric and adjust the foundation chain on a new project if needed.
The border becomes wavy	Too many stitches were worked along the side edges	Undo the affected section and redistribute the side stitches more evenly.
The border pulls inward	Too few stitches were worked along the side edges or the tension is too tight	Rework the side edging with more evenly spaced stitches and relaxed tension.
Color changes leave visible gaps	The new color was not secured neatly or the yarn was pulled too tightly	Change colors at the final pull-through of the previous row’s last stitch and weave in the ends securely.
Yarn ends come loose	Ends were woven in too briefly or in only one direction	Re-thread the end through several stitches, change direction, and trim only after securing it.

14. Frequently Asked Questions

What is a crochet baby blanket inspired by a swaddle blanket?

It is a handmade blanket with a simple, flexible fabric and a shape often associated with traditional swaddle blankets. This pattern creates a square blanket with a decorative border, but it is not a certified swaddling product.

Is this pattern suitable for beginners?

Yes. It uses a foundation chain, half double crochet rows, and a simple single crochet border. The most important habits are counting stitches and measuring the fabric as it grows.

Which yarn is suitable for a baby blanket?

Choose a smooth, soft yarn that is appropriate for blankets and can be cared for according to its label. Cotton, acrylic, and suitable blends are possible options, depending on the texture and washing requirements you prefer.

How much yarn will I need?

Approximately 700–900 yards is a planning estimate for the sample size. The actual amount depends on your yarn, hook, tension, and border. If possible, have a little extra yarn available for finishing.

Which crochet stitch is easiest for beginners?

Single crochet and half double crochet are both beginner-friendly. This pattern uses half double crochet for the main fabric because it works up at a practical pace while creating a flexible texture.
