You will need:
Spray Paint (Red and Black)
Step 1: Laser Cut
Laser cut the two files out of acrylic. You can use any material that will withstand the paint including paper. We recommend acrylic if you plan on making a reusable stencil.
Step 2: Paint
Use the "Red" file to spray the first layer. Once it dries, align the second stencil, file "Black", over the original paint, and spray.
Step 3: Enjoy
Kick back and enjoy a job well done.
