Shells Aflutter 12 Inch Afghan Square – Free Crochet Pattern

I absolutely love designing afghan squares! I love when an idea starts to form and ends up flourishing into something breathtaking. My Shells Aflutter 12 inch afghan square started out as something totally different than what it is now and I couldn’t be happier with it! It wasn’t easy to create but that was the fun of it, just seeing where the stitches would take me. I hope you enjoy this gorgeous square and turn it into an amazing afghan! Happy crocheting!
