I'm giggling just a little bit! First off, your quilt is fabulous! When I read your title to this thread, I thought TGIQ meant "Thank God It's Quilted" because you finally finished it after all the trouble you had with it. Then I read your first posting about it and realized that it meant The Great Illusion Quilt!!!
I don't know how you did it, my anxiety level started to rise just looking at the blocks that you made! Great Job!
