Step 2: Prepare the tray
We want to cover both of the long sides of the tray with double sided tape.
Put a long strip of tape on the long sides of the tray and cut away exces tape with the exacto knife.
This is the part where you can put blood, sweat and tears into the project. (if you're not careful with the knife)
Don't forget to peel away the layer covering the other sticky side.
Drink from your coffee.
