I don'thave kiddies in school close by, but I have made over boxes (soda flats/ or beer if ya drink enough) with each of my G/kids names on them. They sat on top of the refrig and collected some of the greatest pieces of art work ever brought home!!
I used those big manila envelopes for my own children back in the day..
easy to decorate and add names to..then when full, just date and add a new one!! Kept mine on a Cork Board at the kids level so they could add in their pages.
Sorry No pictures, but I hope this gives someone an idea or two.. collecting, sorting and keeping papers from school is a big mess unless ya got a "system"..
