Using this unfinished Virgo sign shape for your zodiac craft is a breeze. First, peel off the protective paper backing that comes on most of these crafts. This was there to keep the wood safe during laser cutting and shipping. You can use it as is, or add a hole if you need one. Just tell us the size and location, and we'll add it for free. As for the size, you can choose a diameter from 3 inches up to 36 inches. The wood is made from cabinet - grade Baltic birch plywood in 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) thickness. If you need a different thickness, just send us a message. When it comes to maintenance, keep the wood away from excessive moisture to prevent warping. If you want to paint or stain it, make sure the surface is clean and dry. That's all you need to know to get started on your amazing zodiac craft project!
