Using your unfinished wood sheep - shaped craft is a breeze. First, peel off the protective paper backing that came with the craft. This paper is there to keep the wood safe during cutting and shipping. You can customize it as you like. If you need a hole in it, just tell us the size and where you want it, and we'll add it for free. When it comes to size, you can choose a diameter from 1 inch up to 36 inches. As for the thickness, we offer 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) cabinet - grade Baltic birch plywood. If you need a different thickness, reach out to us. To maintain your craft, keep it in a dry place to prevent warping. And if you want to paint or stain it, make sure the wood is clean and dry first. Have fun with your crafting project!
