Open the download to see the illustration. I would use a square block that is 2 inches larger than what you have. Round the edges of your star block so they match or cut out more of the set together white, Turn edges under or edge with a tight stitch zig zag or decorative embroidery stitch. If the edges are turned under, then applique by hand. If you want the edges zig zaged on the machine, place your block on the larger square and applique with machine. If you have a wide enough and close enough zig zag, no need to turn edges under. I used the zig zag method with the sunbonnet sue in the middle of the down loaded quilt for my granddaughter.
