I made 2 different sizes - one using 2.5" squares and the other using 1.5" squares. (And there are a couple of rectangles in there too.) The big one ended up finishing at 8" and the little one is 4" finished. This block was a 6" block in the original column. But I just decided to use the sizes of squares I frequently cut. The purple and yellow ones came out of the tin box holding my postage stamp cuts (from my scraps). The red and blue ones came from some strips in my scrap bin. And I always have lots of white scraps left over from other projects because I like white backgrounds.
Check out Bonnie's Addicted to Scraps links. http://quiltville.blogspot.com/p/addicted-to-scraps.html The links with the block titles will take you to the Quiltmaker magazine site although the patterns are not online.
These only took 15 minutes including the cutting time. More of these are undoubtedly in my future.
