These are slips to give parent for when they send money to school. If you are like me, there is occasionally a $20 dollar bill that gets left on my desk in the morning. When I inquire about who put it there and what it is for, I sometimes get no response from the kids.
I saw something similar to these on Pinterest but the link had a warning that said people had reported it as spam and could harm the computer so I discontinued the search and decided to remake them. If this is your idea, please let me know and I will either give you credit or remove my version.
