You will use actual tin coffee cans or vegetable cans
The first step is to punch holes in the bottom for drainage and drill the holes in the back for hanging. Use the hammer for the drain holes and a drill with a metal bit for the rope holes. Make sure you get it just big enough for the rope to go through, not too big.
Give ’em a few good coats of spray paint. However many you need until it looks good. Let them dry.
Put one of the rope through one of your rope holes and knot it. Then decide on your length and cut the other end accordingly. Knot that end through the other hole.
Voila! A hanging pot!
