Using these unfinished wood flower - shaped crafts is a breeze. First, peel off the protective paper backing that comes on most of the crafts. This paper is there to keep the wood safe during cutting and shipping. If you need a hole in your craft, just tell us the size and where you want it. You can use these crafts for all sorts of DIY projects. They're made from cabinet - grade Baltic birch plywood in different thicknesses (1/8, 1/4, or 1/2 inch). You can choose the size that suits your project, as they range from 2' to 24'. When it comes to maintenance, keep the wood in a dry place to prevent warping. If you paint or stain the wood, follow the instructions on the paint or stain product. We make these products by hand in the suburbs of Pittsburgh, so you know you're getting a high - quality item. And if you have any questions, don't hesitate to message us!
