I have never made any jewellery, but once I get my hands on some other stuff I have a project I want to try that I think will make pretty things to hang on cords or leather. However I don't know how to make a cord fasten at the back if you see what I mean. I am sure there must be some kind of end cap that you crimp onto the cut ends of the cord that a fastening device would then attach to but as I don't even know what such a thing is called I have no idea how to find what I want - can anyone help me please.
