Nancy's notions has a kit that allows you to sew prefect circles with your sewing machine. I believe you can sew them up to 20+ inches in diameter. I plan to make the orange peel quilt for my guild's show this coming fall. I am new to quilting and thought this would give me a fighting chance to complete a quilt on time. I do plan to put Warm and Natural inside each patch so it can be used as a winter quilt. I'm sorry but I don't remember the name of the item in the catalog.
