I agree that teachers receive too many sweets, so I found this website that you can make soup mix in a jar. It is very attractive, especially if you cut a square cloth (about 8X8 inches) cover the lid, and tie it with ribbon. It is a great way to make multiple gifts and is very inexpensive. Usually it ends up costing about 6 dollars a jar. Another bonus is it is fun for the kids to help out with, and it teaches them about measurements. Here is a link to a website that has a variety of recipes.
