Loving this image of old tins being used for plants nestled amongst the books. I love retro packaging, especially tins (coffee, tea, cigars), and turning them into vases is a great use!
(Bottles too-- I saved an image a while ago that I now can't find of old brown bottles lined up on a mantel with white flowers coming out of them that I absolutely loved.)
I like this idea for using tea tins too...
