Save time and money....
Count out how long you want your chain to be (1 inch, 12 links, whatever). Once you have your ideal chain length, take a tiny piece of wire (I use 26 gauge depending on the weight of the chain) and thread it through the top link of the chain.
While holding the wire with the chain hanging in one hand, thread another uncut chain link through the wire.
Let it hang down then cut it so it is even with the first chain length.
It's so easy and quick!
