Iโm so excited to show you my latest design called Clamshell Stitch Square Crochet Blanket because completing some big project is always acompanied by such a feeling of relief and accomplishment!
If you follow my work, you may remember the Clamshell Shawl I released earlier this year.
From the moment I started working on the Clamshell Shawl, I knew I wanted to make a square blanket using the clamshell stitch pattern as well.
Not only is this stitch pattern colorful and cheerful, but also very versatile.
This Clamshell Stitch Square Blanket is worked in the rounds from the center out.
It features a scallop-shaped pattern which uses only basic stitches and creates amazing structure.
I recommend you to use two or more colors for this pattern, because its beauty lies in changing colors with every clamshell.
The best part about this blanket is the easy size markers. Just add a few more rows depending on how large you want it!
Not only is this clamshell stitch square blanket pattern a sweet treat for your eyes, it’s a cozy cover you’ll love wrapping up in while relaxing.
DK weight, Scheepjes’ Softfun yarn makes this crochet afghan even more cuddly than you could’ve thought possible.
Have fun choosing whichever colors you like and make this clamshell stitch square blanket for your own home or share its sunny cheer with a friend and make it as a gift.

Then, repeat Rounds 5 โ 28 until desired length.
NOTE: If you want to follow my color pattern then work:
Rounds 28 โ 30 with Yarn A,
Rounds 31 โ 33 with Yarn B,
Rounds 34 โ 36 with Yarn C,
Rounds 37 โ 39 with Yarn D,
Rounds 40 โ 42 with Yarn C,
Rounds 43 โ 45 with Yarn E,
Rounds 46 โ 48 with Yarn B,
Rounds 49 โ 51 with Yarn C,
Rounds 52 โ 54 with Yarn D,
Rounds 55 โ 57 with Yarn E,
Rounds 58 โ 60 with Yarn A,
Rounds 61 โ 63 with Yarn B,
Rounds 64 โ 66 with Yarn D,
Rounds 67 โ 69 with Yarn E,
Rounds 70 โ 72 with Yarn B,
Rounds 73 โ 75 with Yarn C,
Rounds 76 โ 78 with Yarn D,
Rounds 79 โ 81 with Yarn E,
Rounds 82โ 84 with Yarn A.
When you have the desired length, I’d recommend that you end on either a repeat of Round 6 or Round 9 or Round 12 or Round 15 or Round 18 or Round 21 or Round 24 or Round 27, so you finish with a fabulous scalloped edge.
Fasten off yarn, weave in all ends and block your blanket.
