This craft company in Texas sold these strips of leather with a snap on each end and two cuts to make a braided bracelet.
They leave the braiding to you for fun and bragging rights.
You can do this with any piece of leather or even heavy cloth, making it as long as you want.
I was surprised when I first saw it because I'd done a lot of braiding but not with both ends closed.

I found it in my desk looking for something else, it's probably been posted before but it's a trick that always surprises folks who haven't seen it.
