This week we are learning to crochet the interlocking shell stitch. This stitch features rows of shells and clusters that create a unique ripple pattern. We made it to block #24 (the last one!!) of the 2019 Stash Busting CAL.

If you aren’t a part of the club, you should join us, show off your squares and ask your questions, either I or one of the other talented crocheters in there are ready and willing to help.

If Instagram is more your style, don’t forget to tag me (@theunraveledmitten) in your pics and use #2019StashBustingCAL.

I’ve been getting lots of questions about joining our squares and I just wanted to put it here that I’ll be giving you a tutorial on my favorite join as well as suggestions for alternative ones. You are free to join them however you choose. I’ll also be doing a tutorial for a border.

Interlocking Shell Stitch Tips and Tricks

This fun stitch would be suitable for a variety of different projects: hats, scarves, blankets and more! I changed color every 2 rows for mine (mainly so I could carry my yarn up the side of the square) but it also looks nice in solid colors and stripes every row. 

The thing I like about this stitch is it has a ripple or wave effect but has flat edges! This makes it easy to add any border you may want

The first row is a row of 5 dc shells. Then on the next row, instead of nesting a shell stitch between the shells of the previous row, you’ll double crochet 5 stitches together using 5 stitches from the top of one shell to the next to create a shell cluster.

    I don’t seem to be doing this right,,I have big bubbles where I am doing the dc5tog,,there is no way that mine will lay flat, even when I block it. What am I doing wrong?
