My husband brought home a cute little thing that they gave out at work for the employees and I revised it a little so that we could hand it out for Teacher Appreciation. I just typed up a copy of it, put the stuff in a bag and taped it on the front and gave one to each of the primary workers. It ended up costing only about 50 to 75 cents a piece to make.
