I have some beautiful and small ceramic snowflake ornaments that a friend gave me as thanks for watching her dog one Christmas break. I have since lost touch with her and don't know how to find her (her name is common and she's very private). I always think of her and say a little prayer when I hang them on the tree. Sadly, I started with 12 and I think we've dwindled down to about 6-8 since she first gave them to me. I try to be very careful but I think some have gotten lost in the tree and thrown out. :(
Also, my Fontanini nativity set that my MIL gave me when we were first married. I've added on to it because I love it so much. They're very realistic, but plastic, so indestructible with little hands.
