Yesterday at church we were handed a massive stack of egg cartons, the non-styrofoam type (yes, I farm out prep-work, lol, and have people saving egg cartons for me), and hubby casually mentioned something he learned in the boy scouts. He said they would cut apart the carton into little individual sections, then fill them each with lint and sawdust, then cover the whole thing with a thin layer of paraffin wax, and use it for starting fires. I thought that was pretty brilliant!

Another use for egg cartons, only the non-styro ones, is to use them as seed starters.
