This Instructable will tell you how to make a simple or complex design on a a piece of aluminum. With a hammer and a nail. The reason I made this was because this part of my wall was very plain and boring and it needed some air holes for the microwave so I made these. Really brings out the wall now.
Step 1: Getting all of the supplies.
You will need a hammer, a nail (the size of the nail will determine the size of the hole), a board, a design you drew or got of the internet, some duct tape and a piece of aluminum (or copper).
