Its more of a charm bracelet than a friendship bracelet but still.
Anyways how you would make this in real life is you get a string tie a knot in the end (make sure its big so the beads dont slip of that happends to me a lot), Then you buy or make beads to put onto the string, Then you put the beads or charms onto the string in thee order you would like them, Then you can tie it on your wrist or what I do is tie it so that it can tighten and come off easy, Then there you go unless you're making them for some friends then just keep on doing this until you have enough bracelets.
