Using these unfinished wood bowl shapes is easy. First, peel off the protective paper backing that comes on most of the crafts. This backing is there to keep the wood safe during laser cutting and shipping. If you need a hole in your bowl shape, just tell us the size and where you want it, and we'll add it for free. You can use these bowl shapes for all sorts of kitchen crafts. When it comes to maintenance, since it's natural wood, keep it away from excessive moisture to prevent warping. If you want to paint or stain it, make sure the wood is clean and dry. You can sand it a bit more for a smoother finish if you'd like. We ship these products within 24 hours, so you can start your DIY project soon. And if you have any questions, don't hesitate to message us.
