How about a version of those Advent calendars that have 24 little boxes/compartments to open? You could send something to arrive on November 30th, with 24 small boxes or envelopes. You don't need gift boxes, although you can use the stuff you save for "just in case" occasions - but you can also use envelopes, little bags made out of seasonal cellophane, even things like toilet paper tubes wrapped in Christmas paper. Gifts can include anything:
- $1 lottery tickets (spread them out, maybe 1 per week)
- Christmas candy or cookies - homemade or his store-bought favorites from childhood
- a few postage stamps and addressed envelopes (to you, to Grandma...)
- an article you think he would enjoy, or a cartoon
- a "coupon" for anything you can do - homemade meal (I know he's a chef, but hey, you're his mom), a board game night around the fire, a TV movie together whenever he gets time off, and so on - be creative
- small toiletries - travel size toothpaste, shave cream, deodorant, lip balm, etc.
- a gift card for stuff he might like, even if it's iTunes or a game for his phone. A silly $1.99 check would be funny because you thought of him.
- homemade jelly or pickles from a local farm stand. He's a chef, but he can't get hometown stuff like that.
Have fun with it!
