Calling all Cereal Box Cardboard!

Hi all, in preparation for a craft project at the end of next week, if you have an old cereal box at home please could you send it in with your child either tomorrow or Monday. It can be any thin card box so a tissue box / tea box etc would work well also. As the boxes will need to 'quarantine' for three days before we use them, bringing it in tomorrow or Monday would be ideal. Thank you.
