Would you like a necklace longer or is your neck too big for a necklace you love? No problem, a chain extender will allow you to wear or lengthen any necklace. Have available an open ended jump ring and attach it to the ring on the necklace you are going to enlarge. After you have attached the jump ring, take your long nose pliers and pinch closed the jump ring. Now you have attached the extender and you can put the clasp of the necklace through any of the links in the extender. Remember necklace extenders can be put on jewelry you make or it can be put on jewelry you buy in the store.
