This is not a fund raising idea but it will get you supplies an easy way.
Each child in our school would get a list of supplies to bring to school.
The art teacher was able to add to the class lists 1 extra thing. Then
these supplies were pick up. Ideas were paper plate for paints, zip lock bags
for storage, kleenex, sponges, etc. We spend so much of our money on these
type of supplies that it really cuts into our budget. Also at the end of
school we asked for donations of any supplies the kids didn't want to take
home. We had paper bags with names on them for each class and they were
emptied as they fulled up that last week or so before school was out. We had
a girlscout troop take this on and the supplies went to another school
without an art budget. But it can be used for your school too! Good luck!
