Hello Moonpi,
I'm trying very unsucessfully to do a n attic windows baby quilt. I see you cut your sincow sills longer than the block. Do you cut off the bottom tags on those? I am sure I cut my sills to short because they aren't coming together right. I'm almost re ady to through in the towel and just do blocks. I saw one that just did half square triangles in the corners. Guess I could try tha way. I printed the side template pieces on line some where and have cut a lot of them hoping I don't run out of one of the fabrics. I made 5 inch blocks. Any ideas you have will surely help. I saw another one on here somewhere that seems like you helped on. Hope you have ideas.
