All we used to make this was a crate, some scrap PVC pipe and a piece of scrap wood. The crate is from Michael's and was about $14. (We used a 50% off coupon.) Overall, we spent a whopping $9 on everything! I do like the look of natural unstained wood, but I wanted it to look a little more polished so we put one coat of light wood stain on the crate. And because our little boy has cars and trucks of all shapes and sizes we decided to incorporate two different size PVC tubes to accommodate them all. The tubes fit very tightly in the size crate we used so we didn't think it was necessary to glue them in. But, if you used a different size crate or PVC you could easily hot glue them in to secure them, as well.
