This is a bracelet made from a simple i-cord. I used some leftover Bernat sheep (ish) for the one pictured, but I’ve also had success with cotton yarns, which become less frizzy with wearing.
You can make it as long as you want it to be, I like it to be able to wrap around 3-4 times.
You can connect the ends by tying them-I used a lobster claw, a very large one so it would be easy to thread the yarn through its hole.
