Yesterday was Emily's birthday, so I made confetti. I threw it "in nature" (meaning, a half-mile away at the bus stop) so I wanted it to be eco-freindly and biodegradeable...and not require me to go back down there with a broom and sweep it up. A little research to see what biodegradable paper I might have on hand revealed...toilet paper. Yes, all toilet paper is biodegradable, some more than others. (This fact was discoved by a young person doing a science fair project -- here's a clue for your own science fairrier, which is the most?)
It took a little experimenting to get the hole punch to go cleanly through the paper. It required 4 folds -- 8-layer thickness -- for the hole to punch cleanly. I'll just say that this will execrcise your hands, so if you need a lot of confetti, do it over time. I made a couple of handfuls in one sitting. I puched them out onto a large piece of scrap cardboard, then used a paintbrush to dab the pieces with watercolor paint, leaving some of them white. A single touch of the brush will do it; the painting goes quickly and they don't take long to dry. Hap-py Birthday!
