This past August, the boys and I made fossil medallion necklaces for their treasure hunt birthday party. I've been meaning to share these for awhile but time has way of getting away from me...I also hope to share the birthday party someday - it was a ton of fun! Anyways, I thought these would make great Christmas gift for children's friends or for Aunts and Grandmas. If the ladies in your family aren't too fond of creepy crawlies, you could also use stamps to imprint flowers or names.
