I'm not a teacher, but I'll tell you what I usually do for the teachers at my kid's school. I make jewelry, and during the school year I pay attention to what the teachers are wearing, and then I usually give them something that looks like they would wear. I also like to contribute to a classroom gift. I like this idea because a teacher will get a gift card that has enough money on it to get a nice meal or a couple of books. Five dollars doesn't go far, but several people giving $5 can make a nice gift.
