Take your new nylon guitar string and feed one end into the bridge hole.

To tie the knot, hold onto the longer end of the string with your left hand and grab the end of the short string with your right hand. Wrap the end of the short string back around itself two times. The string should resemble a figure-8 pattern.

Hold down the knot on the bridge with your fingers and pull the longer end of the string with your left hand to tighten the knot.
