Using your unfinished wood house silhouette is easy. First, peel off the protective paper backing that's on most of these crafts. This backing is there to keep the wood safe during laser cutting and shipping. You can use these silhouettes for a variety of craft projects. If you need a hole in the shape, just tell us the size and where you want it, and we'll add it for free. When it comes to sizing, we have diameters from 2' up to 36'. As for maintenance, since it's natural wood, keep it away from excessive moisture to prevent warping. You can paint or stain it as you like to give it the look you want for your project. And remember, if you have any questions, just click 'Message Seller' and we'll help you out.
