Birch Perch. Create shelves with panache using birch logs as supports. Trim sturdy branches to equal lengths, keeping the cuts straight. Paint two 24-inch-long 1x6 boards in the desired color. Attach one board to the bottom of the branches using wood screws, and attach the second board to the top of the branches, again, with wood screws. Hang the shelves using picture-hanging hooks driven into wall studs.
