Crochet Shell Blanket

I’ve made many variations of crochet shell blankets over the years.

Similar to perfecting a chocolate chip cookie recipe, this pattern is the result of making continuous improvements until I could finally say: “This is it… the perfect crochet shell blanket!”

There’s nothing complicated about it; it’s just a lovely, calming pattern that looks stunning when complete. The blanket is soft, snuggly and reversible.

I’ve designed this pattern to be a baby blanket but the size is completely customizable.

Since the pattern uses only single crochet and double crochet stitches, it’s great for beginners wanting to learn how to crochet a shell blanket or for experienced crocheters looking for a relaxing project.

Whether it’s your first or 1,000+ crochet blanket, you can sit back and enjoy crocheting this gorgeous classic shell blanket.

Shell Stitch Crochet Pattern

Materials

Any size 3 (light) yarn. You will need approx. 1,300 yds in total (1,050 yds for the blanket body and 250 yds for the border). Learn more about yarn weights.

I used Feels Like Heaven by Lion Brand in the color “Mauve.” This yarn is size 3 (light) and 100% nylon. A skein is 246 yds / 225 m and 3.5 oz / 100 g. I used 5 and 1/4 skeins. (Note: I’ve also made this pattern using 100% acrylic yarn (size 3) and the results as well as the amount of yarn required were almost exactly the same). 

Crochet Hook Size: K/10.5 (6.50 mm). Learn more about crochet hook sizes.

Other Materials: yarn needle, scissors and a measuring tape. See my recommended crochet supplies.

Easy Shell Blanket Crochet Pattern Instructions

Shell Blanket Body

Start: Chain 104. 

For Row 1 (only) work into the back ridge loops. 

Where to crochet in the chain

Row 1: In the second ch from hook, sc. Sc in each ch across. (103 sts). 

Row 2: Ch 1 and turn. In the first st, sc. *Sk the next 2 sts. In the next st, make a Shell (5 dc sts in the same st). Sk the next 2 sts. In the next st, sc.* Repeat from * to * across. (17 shells + 18 sc sts = 103 sts. Reminder: chains never count as sts.). 

Row 2

Row 3: Ch 2 and turn. In the first st, make 3 dc in the same st. Sk the next 2 sts. In the next st (the top of the middle stitch from the Shell in the previous row), sc. Sk the next 2 sts. *In the next st (the top of the sc from the previous row), make a Shell. Sk the next 2 sts. In the next st, sc. Sk the next 2 sts.* Repeat from * to * across until there is 1 st left. In the last st, make 3 dc in the same st. (16 Shells + 17 sc sts + 6 dc sts (the dc sts that are not in Shells) = 103 sts). 

Row 3

Row 4: Ch 1 and turn. In the first st, sc. Sk the next 2 sts. In the next st, make a Shell. Sk the next 2 sts. In the next st, sc. *Sk the next 2 sts. In the next st, make a Shell. Sk the next 2 sts. In the next st, sc.* Repeat from * to * across. (17 Shells + 18 sc sts = 103 sts). 

Row 4

Row 5 and on: Repeat Row 3 and 4 consecutively until the height of the blanket measures approx. 34” high (approx. 68 rows in total) or your desired height. 

Ensure you end after completing a Row 4. After reaching your desired height, do not fasten off. 

How to Crochet A Shell Blanket

Shell Blanket Border

Ensure you have ended after a Row 4. 

Border Round 1: Ch 1 and turn. 

TOP: In the first st, make 3 sc in the same st (first corner made). Sc in each st across the top until there is 1 st left. In the last st across the top, make 3 sc in the same st (second corner made). 

SIDE (DOWN): Working down the side and into the sts at the end of each row (not the spaces), sc evenly all the way down.

(Need help with where to work into? At the end of each row, there is a dc st followed by a ch-1/sc st that you will work into – either into one loop from the st or two loops. When working into the dc sts, I made 1 sc in the top of each dc st and 1 sc in the bottom of that same st. For each ch-1/sc st, I made 1 sc in that st. The exact stitch count is not important – the goal is to have evenly placed sc sts all the way down the side). 

BOTTOM: In the first ch at the bottom, make 3 sc in the same st (third corner made). Sc in each ch across the bottom until the last ch. In the last ch across the bottom, make 3 sc in the same st (fourth corner made). 

SIDE (UP): Working up the side into the sts at the end of each row, sc evenly all the way up (same as the other side).

Border Round 1

Sl st into the first sc st made in the round to join.

Border Round 2: Ch 1 and turn. In the first st, sc. Sc in each st around, making 3 sc in each corner st (the corner st is the middle sc st of the 3 sc made in each corner in the previous round).

Border Rounds 3, 4 & 5: Repeat Border Round 2.

Shell Crochet Baby Blanket

Border Round 6: Ch 1 and turn. In the first st, sl st. *Sk the next st. In the next st, make a Shell (5 dc in the same st). Sk the next st. In the next st, sl st.* Repeat from * to * around. (Nothing special happens at the corners). 

Your last st in the round is a sl st into the first sl st made in the round. 

As you approach the first sl st made in the round, if you don’t have the correct number of sts to follow the pattern correctly, back up and skip less or more sts between Shells and/or slip stitches to make it work.

Fasten off and weave in loose ends.

And now you have a new Shell Blanket! 

Frequently Asked Questions

Can I Use a Different Yarn Weight or Hook Size?

This pattern was designed using size 3 (light) yarn and a K/10.5 (6.50 mm) hook. You are of course welcome to try different yarn weights as well as hook sizes but the overall look, feel and size of the blanket as well as the amount of yarn required may be different. 

For example, size 4 (medium) yarn may create a blanket that is heavier, thicker and stiffer with tighter stitches.  

As much as I wish I could help, I can’t recommend a hook size for a different yarn weight or tell you how much yarn you will need since I’ve only designed this pattern using size 3 (light) yarn and a K/10.5 (6.50 mm) hook. 


How to Crochet a Shell Blanket

Do I Have to Use 100% Nylon Yarn?

No, you can use any type of size 3 (light) yarn. The yarn that you see in the pictures is Feels Like Heaven, which is a yarn that is 100% nylon. I’ve also made this pattern with 100% acrylic yarn (size 3) and the results as well as the amount of yarn required were almost exactly the same. I can’t speak to the exact results using different yarn types or blends but as long as the yarn is size 3 (light), your blanket should be similar. 


Does it Look the Same on Both Sides?

Yes, it does! The blanket is completely reversible. 


Crochet Shell Baby Blanket Pattern

How Many Chains Are Required to Make it a Different Size?

Making 104 starting chains creates a blanket that is approx. 29” wide without the border (33” wide with the border). You can adjust the width by making less or more starting chains in multiples of 6 + 2 (meaning to take any number that you can divide by 6 and add 2 to that number. For example: 600 + 2 = 602 starting chains). To adjust the height, make less or more rows.

I really wish I could tell you the exact amount of chains that are needed to make the blanket in various sizes but I’ve only designed the blanket in the size listed in the pattern. 

As a guideline: 103 sts = 29“ wide, which means there are approx. 3.55 stitches in an inch. You can take the width you want your blanket to be (in inches) and multiply it by 3.55. That should give you a rough estimate of how many stitches you will need in a row for your desired width. Then, round up that number to the nearest multiple of 6 and add 2 – that’s how many starting chains you will need. 

Here’s an example: You want your blanket to be 100” wide. 100 x 3.55 = 355. Round up 355 to the nearest multiple of 6 = 360. Then add 2 to that number = 362. To make your blanket approx. 100” wide, you would make 362 starting chains. (This is a rough estimate and not tested but should give you a width that is close to what you want it to be).
