Does your school send your child home with a stack of flyers and announcements every week? Rather than toss them into the recycling bin (as I've always done), I've taken to cutting them into quarters and stacking them by the phone. I'm always scrabbling around looking for scratch paper, and my kids often ask for drawing paper. Ta-da — self serve, free, and colorful!
Rather than using scissors, I keep my stack nice and even by using this inexpensive Fiskars paper trimmer. I've gotten so much use out of this thing (cutting laser-printed photos, slicing kid art into strips for cards, gift tags and "ribbon," etc.), and you can buy replacement blades when it starts getting dull.
Any other ideas for recycling school flyers?
