Make sure youe under body is smooth. Use a short piece of floss, no more than 10 inches. Be sure your hands are clean. Don't use the rotary function of your vise. Stroke the floss repeatedly while wrapping, at least once every 45 degrees. wrap slowly and watch while you wrap. If the body becomes uneven, unnwrap to an even part and then continue forward. I think Don Bastion has a good tutorial on his DVD.
