I'm totally blown away by the Cathedral Windows. I love the pattern, but never thought I could do one. I watched a friend work on a queen sized quilt, by hand. It turned out beautiful, but I would have gone loony doing it. I didn't even know there was a machine way to do them. I'll have to keep my eyes open for info on it.
Love your patriotic picnic quilt. I, too, love picnics, and this will definitely add to your adventure.
