That is going to be a gorgeous quilt. I made a CW quilt ONCE. I did the background on my machine but when I set in the colored squares, I hand stitched that part. I call is my "Quilt From Hell". It was a king size quilt, purple and white. The center was dark purple and then it got lighter and then back to the darkest purple at the edges. It was gorgeous. I gave it to my daughter. She bleached it. Turned one of the darker purple fabrics into an ugle pink and ruined the overall effect. I could have strangled her! She will never get another quilt from me and I will never make another Cathedral Windows.
