Wrap the jaws of your pliers with masking tape or adhesive bandages to keep from scratching the wire.
Twist multiple wires together neatly using your drill. Just align the wires, insert one end into the drill, and hold the opposite end taut when you start the drill.
Get kinks out of wire by running it over the edge of a table, applying pressure at the same time.
Try not to overwork or bend your wire too much. This can fatigue an area and cause it to break.
Keep track of the wire lengths you use in order to reduce wire waste the next time.
