I have one extra large Clover yo-yo maker, 1 large Clover yo-yo maker and one small Clover yo-yo maker. If you don't have that, then the my cardboard circles should be (1) 4 1/2 inches in diameter, (1) 3 1/2 inch and (1) 2 1/4 inch circle. The size of the circles do not include 1/4 inch seam allowance. Add 1/4 seam to all circles when cutting.
