Good idea for green-living!
I recently found this idea on a site where they built a bookcase from old fruit crates and place it at the foot of the bed. It's a very easy weekend project.
First, start with three sturdy, same-size crates. Stand them on end, and screw them together through the sides. Next, cut a top and bottom from 1-inch boards and secure with screws. If you want to achieve a weathered effect, prime and paint with a base coat of white.** After the paint dries, rub a candle over the edges to resist the second coat of paint. Apply the contrasting top coat. Let dry, then sand to expose part of the base coat. Top with cushions or pillows if desired or display decorative items.
**make sure you use low-VOC paints
