Using this unfinished wood deco border silhouette is a breeze. First, if you ordered it with a hole, you're all set. If you need a hole, just let us know the size and location. Before you start your craft project, don't forget to peel off the protective paper backing on most of the pieces. This backing is there to keep the wood safe during laser cutting and shipping. When it comes to the length, you can choose from 3' up to 36'. As for the thickness, we offer 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you need a different thickness, just shoot us a message. For maintenance, keep the wood in a dry place to prevent warping. And if you want to paint or stain it, make sure the surface is clean and dry. If you have any other questions, just click the 'Message Seller' button and we'll help you out.
