Thank you all. I tried to post a reply earlier, but my 'puter froze up. Meanwhile I've been quilting it all afternoon and I'm using all your ideas. Concentric quilting and various size circles. I'll post a picture when it's done. Having fun doing it. I sent my hubby off to play Rummicube with my friends - we usually go together but I just wanted a silent house and my Sweet Sixteen. Hope he is having fun, too.
