Since you are looking for supplies ask your local newspaper for newsprint.
It maybe in rolls but it worth a try. Ask your PTA for money. Are there in
local clubs that give donations to school. If you wrote a letter and got you
principal to sign it to give to places like WalMart and Sam's Club's. They
give out $25.00 each month to places that ask. It is a start. Remmeber on
this list someone told about giving out paper bags and parents picked them up
at open house and they would fill the and bring them back. You could send a
list out of things they could purchase. Good Luck.
