Jewelry Tutorial - How to Use The Sliding Adjustable Add A Bead Necklace (if you cannot find it online, it means we are temporarily sold out. They're selling fast, but you can email us to be notified when it gets restocked). The Adjustable Add A Bead Necklace will allow you to customize the exact length of your necklace design by sliding the chain along the silicone bead. The silicone filled bead is grippy and will hold the chain in place. There is a spring ring clasp which will allow you to open and lock the necklace. If you wish to make it longer, simply add an extension chain to the clasp. For smaller wrists, the necklace can wrap around 3 times to a layered bracelet. An extension chain would also help make this possible for larger wrists. The 18" chain can also be used as a double anklet - same principles apply. The best part of this chain is a threader that you can add sliding beads to the necklace. The holes of the beads must be at least 1.2mm (the thickness of the chain). It might be advisable to select beads with slightly larger holes because some bead makers make holes smaller than they state on the label.
