Using your unfinished wood closed umbrella shape craft is easy. First, peel off the protective paper backing. This was there to keep the wood safe during laser cutting and shipping. You can customize it as you like. If you need a hole in it, just tell us the size and location, and we'll add it for free. For maintenance, keep it in a dry place to prevent warping. When crafting, you can paint it, stain it, or add decorative elements. Remember, these crafts are made of Baltic birch plywood, so handle them gently. If you have any other questions while using it, don't hesitate to message us.
