I'm in the process(it'll probably take me 4-5 yrs. to finish it) of making a CW quilt too! It is a QAYG type quilt. I'm using the 9 1/2" foundation pcs. with the 2 1/2" inside(window) squares. As you sew around the 2 1/2" inside square this is all the quilting that's needed. It takes four(4) foundation squares to make one (1) block. I'm doing all mine by hand(that's why I say it'll take me so long to finish it) and work a little on it each evening.
