Leafy vegetables make great tasting salads-and sumptuous floral shaped stamps, too. Here, the end of of a head of radicchio yields a rose like print. Cut off stem end with a sharp knife, and stand stem on a paper towel to dry. Press cut side onto a large stamp pad, then onto cards, stationery and more, blotting on paper towel between presses. Vary stamp shapes with other vegetables, such as romaine lettuce stems or even Brussels sprouts cut in half.
