This is an interesting pattern, because it creates one smooth side and one side lined with ridges. I found it quick to work up and fun to create. I did find the “sides” (actually the end of the rows) curled up a bit as I was working. To fix this, I added an extra wide border to hold the edges down. The overall shape wasn’t perfect either, but I don’t strive for perfect, I strive for comfort. In my opinion, machines create “perfect”….people create imperfectly, but with love. I’d opt for “people” every single time. I hope you agree!
