brightlights : Oh yes you can! Once you make those 8 squares. A half of a half a sheet will flush just fine because it's so thin. Look at a paper towel, if you look at it closely enough there's actually two sheets. Pull those apart and start making squares, BOOM!
@eighteen : Not if you live on a septic system. Might flush but the problem will show up later. But in a pinch...uh...dire need, that works.
