Mel, Those are GREAT! The ideas that I have for non candy treats are:
1. Mel's Bookmarks
2. Pencils and/or erasers
3. Pretzels, Raisins/Dried Fruit in snack size ziploc baggy with a topper
4. Crayons with a fun wrapper - I love to buy lots of crayons when they are on sale during the back to school sales
5. Check out the party stores to see what they have in bulk like spider rings, etc.
6. Popcorn - would the school allow carmel corn or popcorn balls?
7. Fruit Roll-ups
If I can think of more...I will pass them along
