I made this Beautiful Pallet Bookcase using three pallets and 5 hours of time. I made this because a customer of ours needed it in their kindergarten class.
Finishing this Beautiful Pallet Bookcase:
I started by framing out the sides. I sanded the pallet wood, but I left some of the rustic charm intact. I built the shelves and mounted them in place. I spaced the pallet boards evenly to give it a little style. I think it turned out great. It could be finished any way you like. You could stain it, paint it, or just seal it.
