Using your Unfinished Wood Gemini Twins Zodiac Craft is easy. First, peel off the protective paper backing that comes on most crafts. This backing is there to protect the wood during laser cutting and shipping. You can customize your craft by asking us to add a hole of a specific size and location for free. Our crafts are available in diameters from 3 inches up to 36 inches, so choose the size that fits your project. They're made from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) cabinet - grade Baltic birch plywood. If you want a different thickness, just let us know. As for maintenance, keep your craft away from excessive moisture to prevent warping. Since it's unfinished wood, you can paint, stain, or decorate it however you like to match your project needs. And remember, if you have any questions, just click the 'Message Seller' button, and we'll be happy to help.
