Real Simple magazine recently published this fun idea for repurposing your Crocs! I thought it was pretty clever, being that Crocs were originally designed as a shoe for gardeners that could be easily washed off after a day in the dirt.
When repurposed as a hanging planter, the air holes turn into drainage holes and heel strap into a hanger. Of course these shoes aren't cheap, but it's a pretty cool idea, maybe if you've lost one shoe or grown out of them and can't use them on your feet anymore!
I could definitely see these hanging around a potting shed, patio, or any other place that has a theme centered around the activity of gardening!
