Beef up your garage or shed's storage with this rustic shelving unit. Made from slatted fruit crates, it's a breeze to build: Just place the crates—check local orchards for extras or find vintage versions on eBay for as little as $8 each—on top of one another, one at a time. Drill pilot holes in the corner braces to prevent the wood from splitting, then fasten with 2-inch deck screws. For extra support, screw the unit into a wall from inside the crates. The resulting shelves are sturdy enough to store pots, plants, even galoshes, and can easily weather any mud or dirt that comes their way.
