I use Velcro with about as much addiction as you seem to be with Hot glue. My only gripe about Hot glue is the little drop that always seems to manage to hit my finger right after the application. You can't just smear it off with your other hand and it cools too fast to run for a paper towel. You just gotta suck it up and take the pain for like 5 seconds until it cools down.
I have been thinking of making a cab out of Legos.
That's an awesome idea. My son has just started to learn the wonders of Lego's. I have not played with them since I was a kid.
Man Legos have come a long way. If you choose to build one (and I would love to see you try) check out the
LEGO Digital Designer . (It is found in the lego factory). You can build the thing on your computer, send the design to LEGO, and they will now send you a kit with the exact legos you need to build it with a picture of your cabinet on the box. You can now buy the pieces by the piece too. I always lost the 1 x 8 flat ones. (My brother and used them as projectiles)
