Using these unfinished oak wood leaf shapes for your fall DIY crafts is a breeze. First, peel off the protective paper backing. This backing is there to keep the wood safe during cutting and shipping. If you need a hole in the leaf, let the seller know the size and where you want it. You can use these leaves in various DIY projects like wall art, ornaments, or centerpieces. When it comes to maintenance, keep them in a dry place to prevent warping. If you paint or stain the leaves, make sure to follow the instructions on the paint or stain product. These leaves come in different sizes from 3' to 24' and are cut from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you want a different thickness, just message the seller. Enjoy creating beautiful fall crafts with these wood leaves!
