Using these unfinished wood bat Halloween silhouettes is super easy. First, peel off the protective paper backing that's on most of the crafts. This backing is there to keep the wood safe during laser cutting and shipping. You can use these silhouettes for all sorts of DIY projects. If you need a hole in the shape, just tell us the size and where you want it, and we'll do it for free. As for maintenance, since it's unfinished wood, keep it away from excessive moisture to prevent warping. You can paint or stain it to your liking, but make sure to let the finish dry completely before handling it. If you have any other questions, don't hesitate to reach out to us.
