I agree with dunster. Your blocks are lovely, don't cut them in half. Someone mentioned the need for a place for your eyes to rest. That resting place is part of the most attractive quilts. I avoided on-point settings for years, but had to just bite the bullet and give it a try because it was a group challenge quilt. My best advice is to take it slow and push your fears aside. Cut the setting blocks as directed. Somehow magic seems to happen and the end result is always beautiful. The side blocks are usually made from large blocks cut in half and the corner blocks are a large block cut in half on the diagonal both ways. Take your time, be brave and move ahead slowly until you "get it" and then revel in the end result of putting your blocks on-point. Courage my quilting friend, courage.
