I was taught this by a gentleman who wears this in copper. I'm not into turning green so, I thought to use Aluminum wire. I've been wearing this for some time and sell lengths of this chain at my local swap meet for various projects.
Step 1: Materials
This is the type of aluminum wire that I use. The size of the wire has a lot to do with the link size. I acquire this wire at my local scrap yard by the usual "buy back" policy. A foot of this wire is not worth much. Its been free and I paid as much as a dollar...... real high end stuff! This black wire here is as big around as my index finger. That would make almost 10 feet.
Step 2: Tools
A razor knife to strip the wire.
Needle nose or chin making pliers.
A pair of wire cutters.
Step 3: First Bend
Almost bend it to a figure 8.
Step 4: Second Bends
More like wraps back around on itself. The number of wraps is determined by how big the link is.
Step 5: Next....
Hook your first link on the eyelet of your next loop. Then just repeat your link.
Step 6: And Again and Again And........
Its a repetitive process and very time consuming.
Step 7: Clasp
I simply cut a link and bend it back on itself. That's just my style. but people also use aluminum clasps like the other photo.
