Using these unfinished wood tombstone shape crafts is easy. First, peel off the protective paper backing. This backing is there to protect the wood during laser cutting and shipping. You can then start your craft project right away. If you need a hole in the shape, just let the seller know the size and location, and they'll add it for free. When it comes to maintenance, since it's natural wood, keep it away from excessive moisture to prevent warping or mold. If you want to paint or stain the wood, make sure the surface is clean and dry. These crafts are available in different thicknesses - 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm). If the standard sizes don't fit your needs, you can message the seller for other thickness options. And don't worry about waiting long for your order, as it'll be shipped within 24 hours or it's free!
