Using these unfinished Baltic birch wood Gothic window shape craft cutouts is a breeze. First, peel off the protective paper backing that comes on most of the cutouts. This is important as it was there to keep the wood safe during cutting and shipping. If you need a hole in your cutout, just tell us the size and where you want it when you're checking out. You can choose different thicknesses - 1/8', 1/4', or 1/2' - and sizes from 1' to 46' according to your project. These cutouts are great for all sorts of DIY projects like acrylic painting, resin pouring, or wood burning. When it comes to maintenance, keep them in a dry place to prevent warping. And since they're made of wood, avoid getting them too wet. Have fun with your crafting!
