Ladies, Always good to check, I purchased a quilt calculator for $19. at joann's on line, the webinar I just sat in on had it for $39.99. Used copies are less than new ones. However, generally if you purchase a book from someone here you also have someone to ask about the quilts they made out of the book. So, I always am glad to help someone out here when I can and the advice is always wonderful that comes with it. So think about it, check it out and then make your purchase. Amazon doesn't give advise on how to make quilts, only buy the books to make them. God bless everyone here for their advise, I am honored to be a member. DianneRAb
