Thank you arleners and tutslady! I'll probably buy the ruler--I found them on clearance on Createforless.com. Arleners, thanks for the link, I favorited it for reference. Just in case you are curious, anybody, this is the quilt I want to make except I won't be using those beautiful Kaffe Fassett prints (one of the best uses I've seen of his wild prints).....
