What Christmas gifts can I make at home to give to co-workers or friends?

I am looking for something small, yet creative to make as holiday presents for co-workers. I work with men as well as women. I need a good idea, not some kid type craft. (I was looking at making etched glass ornaments, but I’m not sure how that would go), I’d love lots of ideas. Something classy since I work with professional people. Any help you can give would be most appreciated.
