I can also provide you with good ideas for overhead shelves. My garage has a 24" deep shelf all around the walls, 24" from the ceiling, attached to the walls and suspended from the ceiling. Easy to do, and I've got TONS o' shit up there. I also constructed a platform or "loft", and it's loaded too. I've got an entire CJ5 Jeep in my garage all in pieces, and a huge amount of it is all up above. Plus Xmas lights, camping/fishing stuff, half a Harley dresser, and more general crap than anyone needs.
