Using this unfinished Ohio state - shaped wood craft is a breeze. First, peel off the protective paper backing that comes on most of these crafts. This backing is there to protect the wood during cutting and shipping. You can customize it as you wish. 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 sizing, you have options from 6' up to 24', and it's made from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you need a different thickness, reach out to us. For maintenance, keep it in a dry place to prevent warping or damage. And if you have any questions while using it, don't hesitate to message the seller.
