I saw this one in Quiltmakers Addicted to Scraps for May/June. It always puzzles me that Bonnie Hunter uses different directions in her columns and blogs than she does in her books. I am such a huge fan of the easy angle ruler after using it for her mystery quilts. So when I see the directions for cutting squares 2 7/8 inches, I usually just grab my precut strips and ruler instead.
I used the easy angle ruler of course, with 2.5 inch strips of yellow and green fabric placed right sides together.
