Apartment Therapy LA posted about SleepyHappy’s inspiring wall garden, made from spray-painted repurposed tin cans. As she notes in her photostream:

Pizza restaurants go through dozens of these cans every week, just ask.
Painted with rust paint these looked pretty good for two years, the third year I did touch ups on the rust that was showing.
Kinda toxic process – not recommended for edibles, but oh so gorgeous for flowers. Rust paint comes in a dozen colours these days!
