Thanks, now I just have to decide exactly what size to start with.that's not going to be too fussy to keep accurate.
I was at a sit and sew on Tuesday and stumbled on a great fabric (guild owned), then another for the backing and I already had a purple for the third color. I think it will be a really bright, cheerful lap quilt. It's not quite light where I am, so I'll post a photo later today.
Thanks so much for your help..
