I was really looking forward to doing this stitch, but mine didn't turn out as well as I'd like. It doesn't look too bad, but it's not as neat as the book's photo. Perhaps I should have used a smaller hook (seems to be an ongoing trend). However, I feel like I learned more about previous row stitches again as well as interpreting patterns and experimenting with possible variations (aka trying to figure out what the pattern wants), as I was confused for a while in the beginning and had to start over.
I used a K hook with Red Heart Super Saver Medium Purple yarn.
