Repeat with the left leg.

Pull the string taught against the end of the leg and place it on the peg.

Pull the end of the string up and thread it under the same string. Pull tight so the string inserts itself in that notch.

Grab the string from the right leg and pull it underneath its own string. Pull tight.

This is what the string looks like when correctly tied.

Carefully lift the base and gently pull the string to test the movement. Don’t pull the limbs off the pegs; you’ll need to retie the string.

The limbs should fall when the string is loose and shoot up when the string is pulled.

You won’t get the correct movement if the string isn’t tried correctly. Pull it out and retie the string.

Keep the ends of the string together and tie a knot. Repeat about an inch down.
