Set of 6 circles marked every 1/2" across. The smallest of the set is to be stitched on the inside to make the 1" circle. The rest of the set is to be stitched around, and the diameters are 2 1/2", 4 1/2", 6 1/2", 8 1/2", and 10 1/2". Allowing for a 1/2" wide foot on the machine, they will stitch out 1, 3, 5, 7, 9, and 11 inches. If your foot is a little wider, your circle will be too. Instructions and design ideas included.
