#1 An Old Ladder Bookshelf If you happen to have an old wooden ladder lying around somewhere, why don't you turn it into a beautiful, vintage-looking bookshelf? It's incredibly simple, cheap and the result is just amazing. What you need is an old ladder (duuh …), and a few “L” shaped brackets. Just mount the brackets to your wall and attach the ladder to them.
#2 Skateboard Bookshelf This is a wee-bit more complicated than the previous one. For this project you'll need 2 old boards, 2 “L” shaped brackets, 2 threaded rods, 8 metal nuts, 8 washers, 8 screws and a drill. Begin by drilling two holes on each deck where the skateboard trucks were. Put a nut and then thread a washer on each of the rods about 10 centimetres from the tip. Put the rods into the drilled wholes and thread a washer and a nut on the opposite side. Before tightening the nuts make sure the rods are even. Do the same with the other board. After you've done with that, take the “L” brackets, attach them to the bottom of the top deck using the screws and then mount the whole set to the wall.
#3 Wooden Pallet Bookshelves This type of DIY bookshelf project is also incredibly easy to make. You'll need a wooden pallet, a saw, 2 planks in the width of the pallet and some screws. Simply saw the pallet where the black marks are, then screw one plank where the red marks are and the other on the opposite side of the pallet. Then attach the new shelves you've got to the wall. And that's it. All that's left to do now is to put your favourite books on your new pallet shelves.
