Does anyone have some ideas for inexpensive, easy to mail Christmas gifts?

I'm quite strapped for cash this year, so for family and nearby friends, I'm looking into various cheap homemade gifts, with holiday cards going out to most other friends who live far away. However, one of my best friends lives in Arizona (I'm in California) and I'd like to send her a small gift as well. Something inexpensive but thoughtful and hopefully something she can put to use.
