Go to the Millwork section of your local mega-hardware chain, in my case, Lowe's. They will have "hobby" wood cut to lengths and nicely edged. I bought a 1x2, 1x3, 1x4 and 1x6 and two and four feet, and simply screwed them together, one at a time starting at the top, leaving a 1.5" shelf on each "step." I sanded them smooth before hand, then after, I stained them and applied polyurethane. I think they look good! Overall price for the wood was around $15-20.00 or so for the larger one.
