SIMPLY GRAB TWO CORNERS (AT THE CURVED EDGES) IN EACH HAND , THEN BRING BOTH HANDS TOGETHER--- AND FOLD IT HOWEVER THE HELL YOU WANT TO. UNLESS YOU WORK AT A SHEET FACTORY, WHO THE HELL IS JUDGING BASED ON THIS CRITERIA?
HOW ABOUT TAKE THE SHEET, PULL IT OVER THEIR HEAD AND BUST THEM IN THE HEAD WITH A PILLOW A FEW TIMES. THEN TELL THEM TO FOLD THE DAMN SHEET.
