I first found Instructables.com when I was looking for instructions on making a chain maille shirt. It is therefore appropriate that this weekly challenge is the first I enter and is simply put "Wire."

Materials needed:
16 Ga. galvanized steel wire
Wire cutters
2 pairs of pliers
Patience

Extras I used to make things easier:
Home made mandrel
drill
coat hanger
Patience

SAFETY NOTICE!
TURNING WIRE INTO RINGS CAN CAUSE DAMAGE TO YOUR HANDS. PLEASE USE SAFETY GLOVES!

Step 1: Making the Rings

I used my mandrel and some hose clamps to create my sp-rings.
Pull a few rounds of wire from your spool. Enough to make a nice foot long spring or so. I use about 15-20 feet at once.
Straighten out your wire to the best of your ability. Clamp one end onto the dowel rod.
Hold the wire in a gloved hand loosely but firmly. With the other hand activate the drill. Hopefully yours is speed sensitive.
Turn the dowel with the drill slowly until you have a spring of wire.
Remove your springs and stand proudly.

Step 2: Cut the Rings

This is tedious as all get out.
PATIENCE!
Cut your rings from their sp-rings.
Store them someplace secure. I use an old butter dish.

You will need one closed ring and several hundred open rings. This is where the 2 pairs of pliers come into play.

Enter clothes hanger.
Put your closed ring on the coat hanger.
Attach an open ring to the closed ring and close it.
This is the tricky part. The 3rd ring. Just look at the picture and make yours look like mine.
Always place the next ring through the bottom two and always from the same side.
REPEAT....

Step 3: Adding Length

Keep adding rings.
Do not worry about the way it looks when you let go of the end.
Re-twist and add a ring. Repeat.

Step 4: Closing

I could not explain the closure of this so Here is the easiest link I could find.
Thanks to the art of chain maille for these finishing instructions.
Unless you are a Knight in the SCA I would not recommend you wear it to an SCA event.
They may frown on the impersonation.
