PTA And Teacher Appreciation

I am a parent and not a teacher. However, my mother is a retired teacher along with having several relatives and friends who are teachers. (I have heard plenty of stories.) I am now serving on a PTA committee responsible for Teacher Appreciation. This committee does various things throughout the year. As teachers what has the PTA done that you found helpful or meaningful to you? I would love to hear feedback on things that the PTA can do to show how much the parents appreciate everything that the teachers and staff do.
