Instructions
Fold the yo-yo string in half.
Open up the string at the fold and place the fold over the axle so that the yo-yo is balancing on the string. Optionally, you may wind the yo-yo string over the axle one more time. This is preferable for most beginners.
Pinch the string about 4inches from the axle and begin twisting it. Twist it until the entire string is twisted and the yo-yo is securely on the axle.
Make a knot at the end of the string so that the two sides do not twist apart.
