This is a great way of making the circles but I learned was wax paper on the back of the inner circle and this was about 10 at a quilt shop in Florida and I have severaI of the circles but I can't figure out how we did it. I'm losing my mind as I mad e a turtle quilt wall hanging and another larger one and they came out great. Willl call a friend in Florida and maybe she remembers We didn't use glue either and it went so fast. But if I cant I will try this one. Thank you.
