Making your own wire connection for leather, rubber cording or fibers is easy. I like the hand crafted look better than some of the premade purchased ones.
This connection is made from 16 gauge bronze wire. First anneal the wire by heating to glowing and quench. If you don't "do fire" you can make it without this step, but it will be a very bright gold tone and not as pliable.
When the length looks nicely balanced for the weight of the cording--no specific amount here, but longer holds better--turn the end up at a sharp angle with chain nose pliers.
Then wrap the end over your pliers to form a loop at the top. Snip off the raw end about a loop and a half down and tuck inside and place on the end of the cord.
Using chain nose pliers, force the raw end of the loops into the cording to grasp and starting at this point work your way up the wire tightening it to fit the cord. "Futz" with it until it's nice and tight and won't pull off.
Don't forget to put a purchased Hook on one end before finishing or make your own hook and attach. If you want the piece to be adjustable you can add a short peice of chain. Using a polishing wheel on a Flex Shaft polish up the finished ends. You can also use OOOO steel wool.
