I sealed all the envelopes, then made a spine with heavy cardstock. I left the good side of the envelope blank so the kids could draw whatever they wanted to and on the sealed side of the envelope I printed two stamps images for them to colour and lots of different mazes to go through.
Its a great way to keep kids entertained and creative and even better way to recycle!
