I like scrappy and I like this. There are so many names! Potato chip I have not heard before. Crumb now, I have done and still work on blocks when I can. I use just about anything under 2.5 inch , but I do square them up. By that I mean no angles, just straight sqs, rectangles,etc. I think when all the colors are together it looks great, even tho you might be unsure at the time. It IS a lot of seams, pinking and ironing!!!! Love this!
