That makes perfectly good sense to me. I am planning to make a fan quilt one of these days and am collecting fabrics for that project.
I have looked at this design in several places but never gave much thought to the fact that one edge on the straight of the fabric would help stabilize the other edge which is more bias than straight. Good thinking!!!
That is the best tip I have gotten and I will remember it when I get to that project. I am making scrap quilts from bags and bags of other people's scrap bins. I love making something out of the things no one else wants.
I will be watching for the other phases of this project. Pleas share more.
