I made a hanging planter out of an aluminum cans, a nail, fishing line, organic seed starter, honey bee seed mix, scissors and a hammer.
Poke holes in the side as well as the bottom. Make 2 holes close to the lip of the can parallel to one another. This will be where you string the fishing line through for your "handle." Fill with your seed starter or potting soil and plant your seeds. Water and hang in the window!
I am planting my honey bee mix so that I can move my planter around the garden when it's time.
