This project is also good for recycling old necklaces. As long as there are two rings at the end for the suede cord to loop on , it is okay.
I use a 3mm wide flat suede, and a piece of costume jewelry.
For step#3 in the image –> Tie the left side cord around the right side cord, not to it. Do so with the other side. Your bracelet is now adjustable. You need to knot it just once. ( The cords are doubled, they’ll stay put. )
Your bracelet is now ready to go!
