Baby Crochet Crib Blanket: A Step-by-Step Pattern for Beginners

A handmade baby blanket is a thoughtful project for welcoming a little one. This beginner-friendly crochet pattern creates a soft, rectangular blanket with a simple half double crochet texture, neat edges, and an optional single crochet border.

You’ll learn how to choose suitable yarn, calculate the starting chain, maintain consistent stitch counts, finish the edges, and care for your completed blanket. The straightforward stitch pattern makes this a relaxing project for both new crocheters and experienced makers looking for a practical handmade gift.

1. Project Overview

Difficulty: Beginner
Approximate finished dimensions: 30 inches wide by 36 inches long
Approximate completion time: 10–16 hours, depending on your pace and experience
Construction: Worked flat in rows
Main stitch: Half double crochet (hdc)
Border: Optional single crochet border
Approximate yarn quantity: 900–1,200 yards of medium-weight yarn, including a simple border

These measurements are a practical starting point, not a universal crib mattress size. Crib mattresses vary, so choose dimensions appropriate for your intended use and avoid creating excess fabric around a sleeping infant.

The blanket is designed for supervised activities, cuddling when appropriate, or use as a handmade gift. It should not be placed in an infant’s sleep space when loose blankets are unsafe.

2. Materials and Tools

Gather the following supplies before beginning:

Yarn: Approximately 900–1,200 yards of soft, washable medium-weight yarn, commonly labeled category 4.
Crochet hook: A 5 mm (H-8) hook is a reasonable starting point for many medium-weight yarns.
Scissors: For cutting yarn.
Yarn needle: For weaving in the ends.
Measuring tape: To check the width and length.
Stitch markers: Optional, useful for marking the first and last stitches of a row.

Choose a yarn that feels comfortable against the skin and has care instructions suitable for the intended use. A smooth yarn makes it easier to identify stitches and maintain consistent edges.

Yarn weight, hook size, and tension all affect the result. A larger hook usually creates a more flexible fabric with more visible spaces; a smaller hook creates a denser fabric. Very tight stitches can make a blanket stiff, while very loose stitches may create large gaps.

Aim for a fabric that bends comfortably, holds its shape, and does not have large openings. No yarn is automatically suitable for every baby or every use, so consider the manufacturer’s care instructions and the recipient’s needs.

The half double crochet stitch

To make an hdc:

Yarn over.
Insert the hook into the indicated stitch.
Yarn over and pull up a loop. You should have three loops on the hook.
Yarn over again and pull through all three loops.

Turning-chain rule

For the main blanket, chain 1 at the beginning of each row. The turning chain does not count as a stitch. Work the first hdc into the first actual stitch, and work the final hdc into the last actual stitch.

For the optional border, the starting chain 1 also does not count as a stitch.

Keeping this rule consistent helps prevent the blanket from gradually widening or narrowing.

4. Gauge and Finished Dimensions

Gauge helps you estimate the finished blanket size and the amount of yarn required. Even if you are not aiming for an exact measurement, checking gauge before beginning can save time and yarn.

Make a gauge swatch

With your chosen yarn and hook, chain 18.
Work hdc in the second chain from the hook and in every remaining chain. You should have 17 hdc.
Chain 1 and turn. Work hdc in each stitch across.
Repeat until the swatch is at least 4 inches tall.
Lay the swatch flat without stretching it and measure the center portion.

For this pattern, a useful starting target is approximately 12 hdc across 4 inches and 10 rows across 4 inches, although actual gauge varies by yarn and tension.

If your swatch is too tight or stiff, try a larger hook.
If it is too loose or has large gaps, try a smaller hook.
If your stitch count per inch differs from the target, recalculate the foundation chain to suit your gauge.

The finished blanket is intended to measure approximately 30 by 36 inches, including the border if you add one. The exact size depends on your swatch, tension, yarn, and border.

5. Understanding the Blanket Stitch Pattern

This blanket uses a simple half double crochet fabric. The stitch creates a subtle horizontal texture and builds quickly compared with many more elaborate stitch patterns.

The blanket is worked flat in rows:

Foundation chain: Establishes the starting width.
First row: Hdc stitches are worked into the chain.
Remaining rows: Hdc stitches are worked into the top loops of the stitches from the previous row.
Turning chain: Ch 1 at the start of every row, not counted as a stitch.
Edges: The first hdc goes into the first stitch, and the final hdc goes into the last stitch.

The repeating sequence is simple: chain 1, turn, then work one hdc in every stitch across.

At the end of each row, count your stitches occasionally. The count should stay the same from the first row to the last. If the stitch count changes, the most common cause is accidentally working into the turning chain or skipping the final stitch.

6. Complete Step-by-Step Blanket Pattern

A. Make the Foundation Chain

For a blanket approximately 30 inches wide after adding a narrow border, begin with 88 chains.

This example assumes your gauge is approximately 12 hdc stitches across 4 inches. With that gauge, 87 hdc stitches make a main panel approximately 29 inches wide, leaving a little extra width for the border.

Make a slip knot and place it on your hook.
Chain 88 stitches.
Lay the chain flat and check that it is not twisted.
Make sure the chain is relaxed and even. Do not pull each chain tight.

The foundation chain includes the chain you will skip when starting the first row. It does not include a separate turning-chain allowance, because the first row begins in the second chain from the hook.

If your gauge differs significantly, adjust the chain count to achieve the desired width. Always work a swatch first if you need a more predictable result.

B. Crochet the First Row

Row 1 (RS):

Insert the hook into the second chain from the hook.
Make 1 hdc.
Make 1 hdc in each remaining chain across.
Count your stitches.

You should have 87 hdc stitches at the end of Row 1.

The skipped chain does not count as a stitch. The row should form a straight strip with no extra stitches at either end.

C. Crochet the Main Blanket Body

Row 2 (WS): Ch 1 and turn. Make 1 hdc in the first stitch and 1 hdc in every stitch across. (87 sts)

Row 3 (RS): Ch 1 and turn. Make 1 hdc in the first stitch and 1 hdc in every stitch across. (87 sts)

Rows 4 onward: Repeat the instructions for Row 2, alternating the right and wrong sides as you turn at the end of each row. Work 1 hdc into every stitch across, maintaining 87 stitches per row.

The stitch pattern does not require increases or decreases. Each row should contain the same number of hdc stitches.

How many rows should you make?

At the suggested gauge of approximately 10 rows per 4 inches, a main panel about 35 inches long will take roughly 88 rows, including the first row.

Use this as a starting estimate rather than a guaranteed count. Measure your work as it grows, because your yarn and tension may produce a different row height.

Continue until the main panel measures approximately 29 inches wide by 35 inches long, before adding the border. If your panel reaches the intended length in fewer or more rows, use the measurement rather than forcing the row count.

D. Maintain Straight Edges

Straight edges come from placing the first and last stitches correctly in every row.

At the beginning of a row, make the turning chain of 1, then work the first hdc into the first actual stitch.
At the end of the row, work the last hdc into the final actual stitch.
Do not work into the turning chain from the previous row.
Count your stitches every few rows. The count should remain at 87.
Use stitch markers in the first and last stitches if those positions are difficult to identify.
Check the edges regularly instead of waiting until the blanket is finished.

The top of an hdc stitch looks like a small V. Unless the instructions say otherwise, insert the hook under both top loops of each stitch.

If the blanket starts widening, you may be working an extra stitch at one edge. If it narrows, you may be skipping a stitch. Correcting the problem early is easier than repairing many rows later.

E. Check the Finished Dimensions

Measure the blanket on a flat surface without stretching it. Check the width across the center and the length from the bottom edge to the top edge.

Before adding the border, aim for approximately 29 by 35 inches. The optional border should add a small amount to the overall dimensions, bringing the finished blanket close to 30 by 36 inches.

If the blanket is too short, continue repeating the main row pattern. If it is already longer than planned, stop adding rows and prepare to finish it.

Remember that yarn, hook size, tension, and washing can all affect the final measurements.

7. Optional Single Crochet Border

A simple single crochet border gives the blanket a cleaner outline and helps the edges look more finished. You can skip it if you prefer a plain half double crochet blanket.

Use the same yarn or a contrasting color. If changing colors, finish the last stitch of the main panel and join the border yarn at a corner.

Border Round 1

Begin at any corner of the blanket.

Attach the yarn with a slip stitch.
Ch 1. This chain does not count as a stitch.
Work 1 sc in each stitch across the top edge.
At the corner, work 3 sc into the corner stitch.
Along the first long side, work approximately 2 sc into every three row ends. Space the stitches evenly, adjusting slightly if needed to keep the fabric flat.
At the next corner, work 3 sc into the corner.
Work 1 sc into each stitch across the bottom edge.
At the third corner, work 3 sc into the corner.
Along the remaining long side, work approximately 2 sc into every three row ends.
At the final corner, work 3 sc into the corner.
Join with a sl st to the first sc.

When working along the row ends, do not insert stitches into arbitrary gaps without checking the fabric. Distribute the stitches evenly so the border lies flat.

Border Round 2

Ch 1. Do not count it as a stitch.
Work 1 sc in each stitch around.
In the middle stitch of each 3-sc corner group, work 3 sc to turn the corner.
Join with a sl st to the first sc.

Fasten off and weave in the yarn ends securely.

How to keep the border flat

If the edge ripples, you may have added too many stitches along the row ends. Undo the affected section and space the stitches farther apart.
If the edge pulls inward or curls, you may have too few stitches. Add stitches more frequently along the row ends.
Keep the three stitches at each corner clearly identifiable so you can place the next round’s corner increase in the middle stitch.
Lay the blanket flat after each round and check that the corners spread naturally.

The border is complete after two rounds. You can add more rounds if desired, but each additional round will increase the finished dimensions.

8. Color and Design Variations

The main half double crochet pattern is easy to customize without changing the basic instructions.

Solid pastel colors

Choose soft pink, pale blue, mint, lavender, butter yellow, or another shade you like. A single color makes the stitch texture easy to see and keeps the project simple.

Neutral shades

Cream, beige, warm gray, or soft brown can create a timeless look. Choose a yarn with enough stitch definition to make counting straightforward.

Simple stripes

To create stripes, change colors after a completed row.

Work the final hdc of the row until two loops remain on the hook.
Yarn over with the new color and pull through the remaining loops.
Ch 1 and turn.
Continue with the new color, making 1 hdc in each stitch across.

This method creates a clean color transition. Weave in the ends with a yarn needle, following the back of several stitches and changing direction once to help secure each end.

For fewer ends to weave in, choose stripe widths of several rows rather than changing color every row.

Contrasting border

Keep the blanket one color and use a second shade for the border. A contrasting border makes the rectangular shape stand out without requiring a more complicated stitch pattern.

A different beginner-friendly texture

You can replace the main pattern with another simple stitch, such as single crochet or a different half double crochet variation. However, changing the stitch pattern may alter the gauge, drape, yarn requirements, and finished size. Make a new swatch and recalculate the foundation chain before beginning.

A larger or smaller blanket

For a wider blanket, increase the foundation-chain count according to your gauge. For a narrower blanket, decrease it. Adjust the number of rows to change the length.

The dimensions in the main pattern are approximate, so use your measurements rather than relying only on a particular row count.

9. Finishing and Blocking

Once the blanket reaches the desired dimensions, finish it carefully.

After the final row or border round, cut the yarn, leaving a tail long enough to weave in.
Pull the tail through the final loop to fasten off.
Thread the yarn tail onto a yarn needle.
Weave the tail through several stitches on the wrong side, changing direction once.
Trim the remaining yarn close to the fabric without cutting into the stitches.
Inspect the blanket for loose ends, skipped stitches, uneven edges, and gaps.

Should you block the blanket?

Blocking may help even out the edges and improve the rectangular shape, but it is not necessary for every yarn or stitch pattern.

If the yarn label permits wet blocking, gently wet the blanket, remove excess water without wringing it, and arrange it on a clean, flat surface. Smooth the edges toward the intended dimensions and allow the blanket to dry completely.

Avoid heat or steam that could damage the fiber. Follow the yarn manufacturer’s care instructions, and do not stretch the fabric aggressively to force it into a size it cannot naturally maintain.

10. Troubleshooting

Problem	Likely cause	Solution
The foundation chain is too tight.	The chains were pulled too firmly.	Rework the chain with a relaxed tension or use a larger hook for the foundation chain.
The blanket widens unexpectedly.	Extra stitches are being added at the edges.	Check that the turning chain is not counted as a stitch and that you work only into actual stitches.
The blanket narrows.	A stitch is being skipped at the beginning or end of rows.	Count every stitch and mark the first and last stitches.
The side edges look uneven.	Stitch placement or tension varies between rows.	Identify the first and last stitch before turning and keep your tension consistent.
The stitch count changes.	The hook is entering the turning chain or missing the final stitch.	Remember that the turning chain does not count as a stitch. Count each row periodically.
The fabric curls.	The tension may be too tight, or the fabric may need gentle blocking.	Try a larger hook if the fabric is stiff, and check whether the edges relax when laid flat.
The fabric feels too stiff.	The hook may be too small or the yarn too rigid.	Try a larger hook or a softer yarn that produces a flexible fabric.
Large gaps appear between stitches.	The hook may be too large or the tension too loose.	Try a smaller hook and check that the fabric remains comfortable and flexible.
The border ripples.	Too many stitches were added along the row ends.	Remove the affected section and space the border stitches more evenly.
The corners pull inward.	There may be too few stitches along the edges or too few corner stitches.	Check the stitch spacing and make 3 sc in the middle stitch of each corner group.
The blanket is too large or too small.	Your gauge differs from the estimate.	Measure the panel and adjust the number of rows or foundation stitches on future projects.
Color changes leave visible gaps.	The new color was not joined securely or the yarn was pulled too loosely.	Change color in the final pull-through of the last stitch and weave in the ends securely.

11. Care and Maintenance

Care for your finished blanket according to the yarn label.

Washing: Use the washing method recommended by the yarn manufacturer. Some yarns are machine washable, while others require gentler handling.
Drying: Follow the recommended drying instructions. Make sure the blanket is completely dry before storing it.
Storage: Keep it in a clean, dry place away from moisture.
Inspection: Check the blanket periodically for loose yarn ends, damaged stitches, unraveling seams, or areas that have become worn.

If the blanket will be used frequently, inspect it more often. Repair loose ends and damaged stitches promptly so they do not become larger problems.

12. Baby Blanket Safety Notes

A crocheted blanket can be a meaningful handmade gift, but loose blankets and other soft objects should be kept out of an infant’s sleep space in accordance with current safe-sleep guidance.

Use the blanket for supervised activities or other appropriate purposes, depending on the child’s age and caregiver guidance.
Avoid buttons, beads, detachable embellishments, long cords, and other components that could present hazards.
Weave in yarn ends and inspect the fabric for loose loops, gaps, and damaged stitches.
Keep the blanket away from an infant’s sleep space when loose bedding is not considered safe.

These precautions do not establish that the finished blanket meets a particular safety certification or is suitable for unsupervised infant sleep.

13. Frequently Asked Questions

Is this baby crib blanket suitable for beginners?

Yes. The main pattern uses only half double crochet stitches worked in rows. The most important skills are maintaining the same stitch count, identifying the first and last stitches, and finishing the edges neatly.

What yarn weight works well for this pattern?

Medium-weight yarn is a practical starting point. Choose a washable yarn with a comfortable texture and follow its care instructions. Adjust the hook as needed to create a flexible fabric without large gaps.

How do I make the blanket wider or narrower?

Change the foundation-chain count. At the suggested gauge, approximately 12 hdc stitches measure 4 inches. Work a gauge swatch first, then adjust the number of chains to achieve your preferred width.

How can I keep the edges straight?

Use a turning chain of 1 that does not count as a stitch. Work the first hdc into the first actual stitch and the final hdc into the last actual stitch. Count stitches regularly and use markers if helpful.

How much yarn will I need?

The approximate estimate is 900–1,200 yards of medium-weight yarn for a blanket around 30 by 36 inches, including a narrow border. Your actual needs will depend on yarn thickness, tension, hook size, and any design changes. If possible, purchase enough yarn from the same dye lot.

Do I need to add a border?

No. The main blanket is complete without one. The optional two-round single crochet border gives the edges a more finished appearance and helps frame the fabric.

Can I use a different stitch pattern?

Yes, but the finished dimensions and yarn requirements may change. Make a swatch with the new stitch, measure its gauge, and adjust the foundation chain and row count accordingly.

How should I wash and dry the finished blanket?

Follow the care instructions for your yarn. Use the recommended washing and drying method, and make sure the blanket is completely dry before storing it.

Can a crocheted blanket be used in an infant’s sleep space?

Loose blankets should not be placed in an infant’s sleep space when safe-sleep guidance advises against them. Use the blanket for supervised activities or other appropriate purposes in accordance with current guidance and caregiver recommendations.

How do I make the blanket softer?

Choose a yarn with a comfortable texture and care instructions suited to your intended use. A hook that is too small can make the fabric stiff, so check your gauge swatch and consider a slightly larger hook if the fabric feels rigid.
