Using these unfinished wood stem and leaf shapes is easy. First, peel off the protective paper backing if your craft has one. This backing is there to keep the wood safe during cutting and shipping. You can use these shapes for all sorts of DIY projects. If you need a hole in the shape, just tell us the size and where you want it, and we'll add it for free. When it comes to size, you can choose from 3' to 36'. The shapes are made from 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm) inch cabinet - grade Baltic birch plywood. If you need a different thickness, let us know. For maintenance, keep the wood in a dry place to prevent warping or damage. Since these are unfinished, you can paint, stain, or decorate them however you like to fit your project. If you have any questions while using these products, don't hesitate to message us.
