I need ideas, please help!

This post is different than any others so far, I am soliciting help from all my creative friends and the ones who think they are not so creative (that's all of you).
School is quickly coming to a close and I have begun to think of what to get each of the kids' teachers to say "Thank You" for all they have done for my kids this year. It is John and Rachel's teachers that I am having trouble with. John and Rachel are in the same class so do I need to get them two things (one from each kiddo) or one thing together. These ladies are also the same ones Elizabeth had two years ago, so would it be tacky to give them the same thing Elizabeth gave two years ago, or do I need to come up with something new? They will also be the same ladies that John will have for the next two years in preschool. Tricky huh?!
Once I get that first issue figured out, the next is what to give. I figure that most of you have done this end of the year teacher gift thing a lot more than me so what great ideas do you have to share?
