TIP: You can sew the yoyo on in several ways. You can sew it on with the sewing machine as I show below here. Or you can hand sew it on or use a zigzag or other stitch on your machine and sew around on the edge. You can certainly use the needle turn method if that is what you are comfortable with. If you are uncomfortable with these you could use an iron on method.
TIP: You can practice with paper to get the feel of sewing a circle with your sewing machine. Cut out a 2” circle and practice sewing it onto another piece of paper.
