You do your part when it comes to the planet.

Taking ecofriendly taxis. Forgoing the night-light. (How many years of therapy did that take?) And though you may not be ready to ditch the SUV quite yet, hey, at least you’re making an effort.

So next time you’re gift-wrapping those all-natural soaps or the bamboo blanket, go green with Shinbum bags. They’re made from recycled Japanese newspapers and are carefully constructed, origami style, by farmers’ wives living in tiny villages on Shikoku Island in Japan. They come in three sizes; give them away with gifts or use ’em to carry home your stash from the local co-op. (Careful: They may be beyond adorable, but, alas, aren’t waterproof.)

They’re sure to spark a conversation. About, say, trading in that SUV for a sleek new hybrid.

You know, for the planet and all.
