There are several books on this. I've never bought one because there are rarely enough patterns that appeal to me to justify the price of a book. Actually, I'm almost done with one I copied, without a pattern, from the Clotilde catalog. The pic of the quilt makes it obvious how to do it, no pattern needed. I'm just making one appliqué block for interest. It took one jelly roll with not much waste at all. Have a bit of leftovers to something interesting on the back. About 40" x 60". Since you know the jelly roll strips are 2" wide, you can actually figure out patterns for many of them. And I'm not especially talented at this, if it strains my brain at all, I buy the pattern.
