This key fob wristlet hardware can come in different widths though – so you need to measure the one you bought to determine what size your wrist strap should be!
You’re going to want to make sure your length of fabric is not too short or too long for a wrist strap.
Sew your folded piece of fabric scrap all the way down the open long edge.
- Pin your safety pin on one end. - Take a chopstick and butt it up against the safety pin on the inside of the tubing. - Gently push/guide the safety pin through using the chopstick.
Using your key fob pliers (or any small pair of pliers), partially close your keychain finding. Put both ends inside and use pliers to finish closing all the way.
