With just a little prep, paint and some new shelf brackets, old floor boards became stylish storage.
Measure the area for the shelves, find where the wall studs are and measure out three inches from there. The shelf brackets must go into studs to be structurally sound, and the shelves should be no more than 3-feet long to handle the weight. Use a tape measure, stud finder and level to mark stud location and shelf placement.
Lay the first board on the shelf brackets. Put it right up to the corner of the walls to determine where the miter cut will start. Use a miter saw to cut the board at that exact angle. Repeat this for shelves above and below.
For the second side of the wall, lay the boards on the shelf brackets. Then lay the already mitered cut boards over the straight-cut boards and draw a line from the mitered board onto the straight board to get an exact match.
Paint or stain the boards as desired. Let them dry completely. For extra stabilization, attach the shelves together at the mitered corners, use flat 4-inch brackets and screw into place on the underside of the shelves.
Place finished boards on the shelf brackets and attached them from the underside of the boards.
