Some things I have done
Stick to your Studies - anything sticky - post it notes, suckers on a stick, pixie stix, tape, silly putty
Keep It Clean - all sorts of cleaning supplies (mine has an apartment), or shower supplies (shampoo, razors, soap, etc.)
Dirty Laundry - detergent, dryer sheets, roll of quarters, stain stick, sew kit, woolite
Exam Cram - coffee, energy drink, stress relief ball, inspirational quotes, granola bars, popcorn, pencils, highlighters, post it note flags
Sealed With A Kiss - chocolate kisses (lots of varieties) lip print kleenex, fireballs
We love you from Head to Toe - A two parter - box 1 with things for their head (shampoo, comb, toothpaste, tylenol, etc.) Box 2 with things for their feet (foot spray, socks, shoe laces, candy gummy feet, etc.)
I am currently putting together her Halloween one - candy, glow stix, eyeball gum, holiday pen, glow in the dark stuff, a toy skeleton
I just did a Goodluck at Your First Friday Night Solo Game (She is an athletic trainer in grad school, working at a high school)
Gobstoppers - to stop all the blood
Band Aids - for all those little owies
Some tape - to stick them back together
Post It notes - to post all the injuries when you get back to your office)
I also saw some dessert kits that you make in the microwave. The pan and all is included. There was Reese bars, Almond Joy bars, etc. Anything they can make in the microwave usually works.
I usually include any newspaper clippings about her high school classmates (weddings, engagements, babies, etc.) Her brothers burn her Cd's and we send pictures of things the family is doing and our pets.
It is pretty easy to come up with things our daughter likes and then make it all fit some crazy theme. She gets a kick out of our crazy ones and the silly ways we try to let her know we are thinking of her. Anything is better than nothing. I also send her tons of freebies from the freebie board. I spell her name wrong so that she knows each time something comes we are thinking of her. The crazier the freebie, the more she laughs.
Goodluck, these years will go quickly.
