Pry open jump rings and slide them over the end links. Close one.
Slide clasp on the other and close ring.
Cut chain so it wraps around your lower waist twice. Attach an S-hook clasp to the right end.
Holding the left end at your left hip bone, wrap the chain, mark the spot where it meets, and attach a jump ring.
Mark a spot at your right hip; make a swag with the chain and attach it with a jump ring to that spot. Drape back with the remaining chain, and loop the S-hook clasp through the left-hand jump ring and a link in the chain to close the belt.
