Using these unfinished wood alpaca - shaped craft pieces is easy! First, peel off the protective paper backing on most of the pieces. This was there to keep the wood safe during cutting and shipping. You can customize these crafts however you like. If you need a hole in the alpaca shape, just tell us the size and where you want it. The pieces come in different sizes from 3' to 36' and are made of cabinet - grade Baltic birch plywood in thicknesses of 1/8 (3mm), 1/4 (6mm), or 1/2 (12mm). For other thicknesses, just send us a message. To maintain these wood crafts, keep them in a dry place away from direct sunlight to prevent warping. You can paint or stain them to your heart's content to bring your DIY project to life. If you have any questions during the process, don't hesitate to reach out to us.
