Rio Grande sells bags like this which, even if I used several per day, will last for a very long time.

I use these quite often as bails on simple pendants. Before I use them this way, I must flatten them out.

I use the flat surface of my wire cutters to do this.

For attaching them to pendants, I kill two birds with one stone. When I solder the split shut, I also am sweating on enough solder with which to attach the ring to the pendant. Notice the relatively large snippets I am using. As always, I am using hard sheet solder.

Flux and heat gently.

Heat until the solder flows.

Notice the nice lump of hard solder on each. This will be useful for attaching it to our pendant.

Here is my simple wire pendant.

I need to find a way to get it perpendicular to the charcoal block to solder the ring on in the right manner.

I've found that using a second pair of tweezers works well for this.

Pick up the jump ring on the opposite side of the soldered area.

Turn your tweezers until the jump ring is parallel to them.

Get a good grip on the ring with the tweezers.

Now flux and heat the pendant and the ring.

Notice that I have my torch in my left hand. This is so I can manipulate the tweezers holding the ring with my right. If you are a lefty, do just the opposite.

You will want to heat the pendant first, almost to the soldering temperature, before bringing the jump ring into soldering position. The jump ring is too small to absorb as much heat as the pendant, and if you have it sitting in the flame while you bring up the temperature on the pendant, you might easily melt it.

Temperature is almost there...

Okay, just about right now, so I will bring the ring to where I want it soldered on.

The solder has flowed, and we're done.

Now we can throw it into the pickle.
