Things you need for this DIY:
✝ a broken necklace
✝ four jumps rings
✝ some chain
✝ a clasp
I never throw things away, like to a fault. I do however reuse things as often as I can. This is a great project for pack-rats like me. I used a broken piece of a necklace that I've had for YEARS.
First trim your piece of broken jewelry, mine was a little under 3".
Measure around your middle finger. Add a good amount of slack.
Take the loop and attach it with a jump ring.
Measure around your wrist, cut the appropriate length of chain and attach the center of it, like so.
Add a clasp and done!
