I have been playing around with cookie cutters and clay impressions, and I have found that I have a small circle and a small heart about 2 1/2″ each that are perfect for capturing little fingerprint impressions. From there, you could add a hole to make it a pendant, add a jewelry pin back to make it a small lapel button, or add a magnet to make it a refrigerator magnet. I also think that these make excellent Father’s Day gifts as a key chain!
