I LOVE buying stuff for stockings! In fact, I think I'll be giving them, or at least goody bags, for my nieces, and maybe even parents!
I buy things all year to put in them, so many that some get set aside for Easter baskets.
For my 14 yo girl, she gets girly stuff, makeup, hair stuff, jewelry, sticky pads, cutesy socks, and pens. She has an obsession with cute pens. Last year I bought her so much stuff, that i was able to fill a small tote bag that I was already giving her with stuff too, and put that under the tree!
The boys get little toys, cards, and whatever else I can find. Maybe a toy sword, and probably books.
This year everyone is getting a flashlight and disposable camera. Also sometimes a gift card, and always candy!
DH gets tools, cable ties, Sharpies, and maybe a small gift.
I get little lotions, paper, pens, and this year I need some gloves, so I need to go buy those...
