Hi Carolyn, I can't help you, having never done an on point quilt, and I'm not even sure about your question, but I can't wait to hear an answer. I'll bet there are tutes, on this site or on YouTube, that show how to do it. Now that the end is actually in sight (over 3/4 done) I know I'm starting to think about how to put it together. I'm planning on staggering my rows with no sashing. But I can't wait to see what others come up with.
