Re: Velcro & Cable Ties
Velcro sounds like one good way to hold your wiring neatly under your layout. For those who can't get the velcro, here's another idea: Releaseable (reusable, unlockable) cable ties. Visit my website in the Parts section and scroll down to "Cable Ties and Accessories" at:
You can get these from Mouser Electronics. They come in a variety of lengths. Use a screw and a mounting block (listed with the cable ties on my website) to hold the wiring under your layout.
