How to do it
Attach the silver-plated wire onto the base and attach the mandrel. Feel free to use different size mandrels.
Keep the wire in place on the mandrel with your left thumb and turn around with your right index finger in the top hole of the base.
Now cut the coil to the desired length or pull it longer if preferred.
Pull the spiral onto the leather cord/cords. Press the ends lightly with a pair of flatnose pliers.
