Instructions
Hold your yo-yo string in front of you so that it reaches from just above your belly button down to the floor. Grasp the string approximately 3 inches above your belly button. Fold the string over and tie a loop in the string at your belly button. Trim off any excess string above the loop.
Pull the yo-yo string hanging down to the floor up and through the loop, creating a slipknot. The slipknot will be used to secure the yo-yo to your finger. Slide the middle finger of your dominant hand into the slipknot and pull the string until the knot fits snugly around your finger.
Split the yo-yo string at the opposite end, opening a small loop in the string. Yo-yo strings are made of two strings wound together, and your yo-yo will sit between the two strings. Slide the yo-yo inside the loop so that the string is looped around the axle of the yo-yo.
Experiment with the string double-looped around the axle to find the best tying mechanism for your yo-yo style. Pull the loop around the yo-yo axle up to make it larger and slip it around the yo-yo axle a second time. Two or more loops tend to give the yo-yo a more positive response.
