This would be by go-to vendor for chains, jump rings and carabiners. You want to check listings to make sure you always order gold-filled and not gold-plated. Gold-filled does not tarnish when it gets wet! When ordering chain (it has no clasp- you’re attaching a jump ring to the end and that slides on the carabiner), order 3 yards to start in case you don’t like it. 3 yards gets you one 16 or 18 inch necklace with a little leftover. Maybe for a bracelet. Smaller jump rings (the 6mm) are good for attaching the charms and larger ones (8mm) are good for either end of chain. Squeeze openings of jump rings and chains once attached together with the tool that has flat sides. Make sure they are nice and shut as much as possible. Real designers solder them shut with heat but do you best without. Charm necklaces, make your own jewelry pieces #LTKGiftGuide
