Every year I go through my scrap paper box and pull out little scrappy stuff & put in some new good paper(well..I actually do this several times a year because I'm a bit OCD). This week my second graders have been creating a collage that is requiring a good amount of paper. HOWEVER....my box seems to be now over flowing?!?! HOW DOES THIS HAPPEN?!?!? ha ha Do scrap boxes reproduce????
