I carpeted my box over the weekend and am pretty happy with it. To make this different than every other thread, i found a new glue for carpeting the boxes. I was too cheap to buy the 3m stuff and also didn't want to deal with overspray or the short set time. So i picked up some Indoor/Outdoor Carpet Glue from lowes. You just spread it on with a trough(sp.?) and then stick the carpet on, its pretty gooey stuff so theres lots of time to work with it to get it taught and look good. After about 5 hours to dry, it was dead solid, i tried my best to rip a piece off and couldn't get a corner. This was mentioned by someone else in another thread, but i just used Marine Carpet from lowes, pretty cheap, around 4 bucks a linear foot(1ftx6ft).
Pics are here, I somewhat impressed myself for my first box.
