Take the guitar string and fold part of it in to a hoop, as big as you need it to fit around your wrist.

Wrap the tail length one around the hoop by slipping it under and over the hoop.

On your second time round slip a bead on to the string before ever wrap.

When you get to the end of your second loop slip the tail through the pick up ring.

Snip off any excess wire and your all done.
