Wow! Love the quilt. Before I saw the quilt I pictured a lot more repeats of the same shape. I'm not sure there would be enough of the same shapes to make a template worth the cost. What about other options like looking through your ruler collection to see how close you can come to some of those shapes so that you can rotary cut. Just recently I made a paper pieced pattern by drafting the shapes without seam allowances on one piece of paper then I sewed, without thread, to mark the pattern on multiple pieces of paper. This would eliminate all of those bias edges. Some people on the Board have made Jenney Beyer quilts, which look a lot like this one, maybe they can give you some suggestions. I know I am all over the map on this one but I think there are a lot easier ways to do this then cutting out each individual shape. Back to the geometry thing (Who knew it was going to have real life relevance, I would have paid attention.), I would look at the degree lines on a large ruler just to see if any of the angles on your pattern pieces correspond. Hopefully you will get some more coherent suggestions. If you don't, I would start another thread, providing the link and asking for suggestions. Please let me know how it goes.
