Using your unfinished wood umbrella shape cutout is easy. First, peel off the protective paper backing that's on most of these crafts. This paper is there to keep the wood safe during laser cutting and shipping. If you need a hole in your shape, just tell us the size and where you want it, and we'll add it for free. You can use these cutouts for all sorts of DIY projects. When it comes to storage, keep them in a dry place to prevent warping. If you want to paint or stain the wood, make sure the surface is clean. Since they're made of cabinet - grade Baltic birch plywood, they're sturdy but still easy to work with. Just handle them gently to avoid chipping the lightly burned edges. And remember, if you have any questions, we're here to help!
