Another shells, luckily we've had a nice break and I was ready to tackle this one. I started out very frustrated though, and it took about 8 or 9 rows before the square started to look like anything other than a giant jumble of yarn. Overall, it's very stretchy and it looks best when stretched a bit, and even then the stitch is still pretty textured. One interesting thing is that the front and back look quite different, which I do like.
I used Red Heart Super Saver Pale Yellow with a K hook.
