Using your unfinished oak wood tree - shaped craft is easy. First, peel off the protective paper backing that's on most of these crafts. This backing is there to keep the wood safe during laser cutting and shipping. If you need a hole in the shape, just let the seller know the size and where you want it. You can use this craft for all sorts of projects, like wall decor, small sculptures, or adding a rustic touch to your DIY creations. As for maintenance, keep it away from excessive moisture to prevent warping. You can sand it further if you want a smoother finish before painting or staining. If you have any other questions about using this craft, don't hesitate to message the seller.
