Using these unfinished wood mushroom shapes is easy. First, peel off the protective paper backing that's on most of the crafts. This backing is there to protect the wood during laser cutting and shipping. You can use these mushrooms for a variety of craft 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. When it comes to maintenance, keep the wood away from excessive moisture to prevent warping. You can paint, stain, or decorate the mushrooms as you like. Just be aware that since they are made of wood, they might expand or contract slightly with changes in humidity. If you're storing them, keep them in a dry place. And if you have any other questions, don't hesitate to message the seller.
