The other day, a neighbor on my Freecycle listserv told me her kid was collecting these:
She asked everyone to help him collect them. I didn't think I'd find any, but what the hey. Couldn't hurt to check. Pulled the old Cheerios box out of the recycling bin and, whatdaya know, there it was. So I flipped over the Kleenex box on my desk. Bingo again!
Into the kitchen drawers, the pantry -- more and more!
