I made it at TechShop.
Step 1: Supplies You'll Need
1. A TechShop membership. Ok, not really a supply but most people don't have access to a laser cutter - if you do have a laser cutter you won't actually need a TechShop membership (but you should probably get one regardless).
2. Enough plywood to fit two copies of the sign you are planning to make. I used 1/8" birch plywood that I got at an art supply store. The plywood you get at art supply stores tends to be flatter, blemish-free, and will fit in a laser cutter.
3. Wood staining and finishing supplies. I used:
a. Minwax Pre-Stain Wood Conditioner
b. 2 contrasting colors of Minwax Wood Finish (I used Pickled Oak and Ebony)
c. Minwax Fast-Drying Polyurethane
4. Wood Glue
6. Rags or a paintbrush for applying the conditioner, stain, and topcoat.
