Using your unfinished wood pierogi - shaped craft is easy! First, peel off the protective paper backing that's on most of these crafts. This was there to protect the wood during laser cutting and shipping. You can use this craft for all sorts of projects. If you want to add a hole, just message the seller with the size and location you need, and they'll do it for free. When it comes to sizing, they're available from 2 inches up to 36 inches in diameter, so pick the size that fits your project best. For maintenance, since it's unfinished wood, you can stain or paint it as you like to make it last longer and look great. If you need a different thickness of wood than the available 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm), just send a message to the seller. And remember, if the item isn't shipped within 24 hours, it's free!
