Step 1: Save and wash various sizes of tin cans.
Step 2: In order to keep the cans from getting dented in when you make the design, it works well to fill them with wet sand and freeze for several hours. We did not freeze our first cans long enough, and some of the sand spilled out. Once they are totally frozen, the sand will stay put.
Step 3: Plan your design. Drew each design on paper, and then attached it to the can with rubber bands. We also tried tape, but it doesn’t stick well once the cold cans start accumulating condensation because of the frozen sand.
Step 4: Use a hammer and nails to punch holes following the design. You might want to have more than one size of nail for details.
Step 5: Spray the cans with spray paint and let dry. We used black chalkboard finish spray paint.
