I bought the circle maker from Nancy Zieman's catalog. It cost me about $20.00. I am hoping to make 2 orange peel quilts for my granddaughter's for Christmas, I have sewn about 40 of the circles and only had minor problems with 2-3 of them. The circles didn't end up meeting as they should have. Operator error I'm sure. I'm very happy with this device and am glad I bought it. The only problem I have had is that I realized that the fabric that comes forward and forms the orange slices is cream colored and I can see the zigzag trimmed seam. I'll know better the next time.
