Stab each kitty figurine with a bead reamer to make a hole for your eye pins.
Once all the kitties have holes on their backs, insert your eye pins.
Cut eye pins to size so that you can attach them to the jump rings.
Once all the kitties are on jump rings, start cutting your chain to the size of your choice.
Attach a jump ring on each end of the chain, then attach your lobster clasp on one side.
Then start attaching each kitty charm to where ever you want on the chain.
Now you are done!
