I had a lot of string blocks that I was squaring up to 4.5 inches. Not sure that I wanted to turn them all into stars, I decided to try this simpler setting. When the string and crumb bits got to small to square up to 4.5 inches, I cut them to 2.5 inches and used those blocks as cornerstones. The sashing strips are cut 2.5 by 4.5 and give the blocks a little room to breath as well as separating the bulk of the seams for easier assembly. I am on the hunt for orphan blocks that I can square up to the same size to mix things up even more. See the little nine patch in the middle? I think I have some more of those somewhere leftover from a photo quilt that I made for my husbands grandmother who has since passed away.
