You need wire cutters, good ones, or tin snips, usually I use tin snips for heavier wire. 
A drinking glass for a mandrel
14-18 gauge round wire of your choice
22 gauge wire of your choice, half round works best, but round or square is fine.
A pair of chain nose pliers
Start with 3 pieces of the thicker wire, 20 inches long
thin bladed knife

Making sure to keep them aligned side by side, wrap the small wire around the middle, and 2 1/2 inches from each end.

Seperate the wires at the ends using a thin knife, and curve them into curliques.

Curve around drinking glass. 

There's your armband! Sorry the instructions are so scanty, but hopefully you get the idea!
