I want to make a snowball lap quilt but don't know how much fabric I need. Want to make the snowballs in various blues, thinking FQ's and the corners in white. Does anyone know or have a computer program that could figure it out for me? I'd really appreciate it. Thanks. The alternative is to buy lots and lots of fabric and while I wouldn't have objected last year, this year with economic situation the way it is, that would be a hardship. Besides, I'm not a "blue" person and would hate to have so much of it left. (this quilt is a gift!) Thanks again. ;-)
