how I replaced the ugly blue garbage can? Sure. Sent one of my kids in, said hey, take that back to your room. Score!
but really, for the boxes - first I got some 1" x 2" x 8' boards, and spray painted them black. Mounted those to the wall, top board right against the ceiling, bottom board about 2.5" below that (used a deck of playing cards as a spacer). Screwed them in to the studs. Screwed right through the boxes in to my strapping...that was about it.
Sucked because I had some very nice boxes that I just couldn't use due to the design, but whatever. Took me probably ~6 hours work total(painted the boards yesterday and let them dry overnight). It was actually pretty easy, I'm NOT at all a "handy" guy but it wasn't a big deal in the least.
