Things You'll Need
Instructions
Slip Knot
Unwind the yo-yo and set it on the floor near your feet. The string should reach your belly button. If it doesn't, you need a longer string. If it's longer, cut it so it's even with the bottom of your sternum.
Tie a loop in the end of the string, so that the top of the loop is even with your belly button.
Grab the string 4 inches below the loop and pull it up through the loop to form a slipknot. Slide your middle finger into the slipknot and pull the string toward the yo-yo. This tightens the slipknot around your finger and keeps the yo-yo string from falling off.
Double Twist Knot
Remove the string from the yo-yo and hold the loop open.
Loop the string around the yo-yo's axle. Keep the loop open.
Twist the string above the yo-yo, so that the loop becomes two loops. One is around the axle and the other is above it. Pass the loop over the yo-yo so two loops surround the axle. Keep the loop open. This step is like wrapping a rubber band around a deck of cards, according to How to Yo-Yo.com.
Twist the open loop once more and loop it around the axle to form the double twist knot.
