This is the begining of my Scrappy green Irish Chain. The squares are 2.5 and the blocks are 10.5/10 inches finished. I have 3 of the 9 rows together and on my wall. I am really enjoying this quilt. I am starting another one that will be completely scrappy for an April wedding gift. I wanted to make the green one first to make sure that I would enjoy the process and the finished quilt. I love the fact that the blocks finish at 10 in. so it makes the math super easy.
