The first method involves using old-fashioned ball chain connectors and a ball headpin.
First, cheat open one of the holes a bit with your pliers, and snap the headpin in as shown. This headpin is made from 18 gauge copper wire (the connector is the size sold to go with the 3.2mm ball chain, and the 18 gauge wire makes a nice, tight fit).
You can also fill the hole by inserting two links of ball chain instead of one:
Unless you get your wrap super tight down on the top of the connector, these will tend to swivel so you won't always see the little beads inside. Sometimes you'll see the back of the connector. In a bracelet or necklace that probably won't matter much, but if you wanted to use this in an earring, you'd need to make sure they didn't swivel around so that the side you want is always facing forward.
Another option is to dress up the ball tip connectors I mentioned at the beginning of the post with a rustic wire wrapped loop. I like this more workman-like look than the plain ball tip connector, and another benefit is that you can use a larger jumpring with it now, or attach it directly to some other element in your piece.
Happy New Year!
