Using these unfinished wood truck - shaped crafts is easy. First, peel off the protective paper backing. This is on there to keep the wood safe during cutting and shipping. You can use them for all sorts of DIY projects. If you need a hole in the shape, tell us the size and where you want it, and we'll add it for free.
