Check out this cute and fun idea of Postcarden. A Structural greeting card that allows you to create your own miniature garden!
"Leagues beyond just-add-water trinkets, this vegetable ink-based greeting card sends sentiments - with seeds. Just pop open the card, water the base, and sprinkle its packet over the diorama. In just a few days, you'll have unruly sprouts of "Lepidium sativum" (that's watercress) furling through the paper arches of your mini botanical garden. "
