I was wondering how some of you bundle wire inside your cabinet.  After some thought I decided to use Velcro held in place using a #8 ¾ wood screw with a ¾ inch fender washer.  They are easy to screw into the wood, will not poke through the ¾ in plywood, can be used over and over, they are cheap, easy to use, and are secure enough to hold the wired in place.  See pictures below.
What methods have you used?
