Found via Miss Frozen Yogurt on Weddingbee, this is a pretty cool idea for personalization of a wedding ring:
They are made by etsy sellers Fabuluster and range from about $125 for the thin and $150 and up for the thick (sterling silver, I think you could probably order a custom made gold ring as well). They send you an impression kit and you send back your fingerprints.
What do you think? Too cheesy?
