Oldest's Christmas stocking stuffer ideas:

mystery paperbacks (Anne Perry and others)

insulated lunch sack for work

navy tights size grande (?)

colorful socks

candles (any size or shape excluding icky sweet smelling)

OPI nailpolish in lightish colors (hands) or sassy colors (feet)

inexpensive funky earrings (prefer gold-colored settings to silver)

any of your cast off books I might enjoy

p.s. Is that Jacob I see lurking in the background?
