i know that this has taken forever to get back to, but I'll try to walk you through a tut.
Ok so first you get 3 loverly bottlecap like these...(I'm a master at paint, cant you tell?)
and next you get your chain, which I'm not going to even attempt making on paint...okay so now on all your caps, punch 4 holes, note that the holes are in different places (the hole punching is done with a good old hammer and nail, i would also suggest doing this on a surface your not really attached to, as it left several dents in my table)
now that the hole punching is done onto the chain! For this I'm not that much help, because i really just eyeballed it, although i can tell you that the chains the farthest down are about 3 links longer that the ones above (oh god now i sound like a math problem!)
So after all of you lovely people who are good at eyeballing things are done with that tighten with pliers, and add another chain for the neck and tada your finished.
This being one of the first times I've done a tut, yes i know its vague and i have no problem if you keep asking me questions about it. i hope that helps at least a little bit, but like i said if its really unclear just ask away!
