Welcome, fellow sheet-folding enthusiasts! I'm Brian McSlothface, the world's greatest sheet-folder. My methods are so advanced, I've got a PhD in Folding-ology.
The McSlothface Fold: Fold the top third of the sheet, then fold the bottom third, then fold the middle third in between. Repeat for 17 iterations, then fold it all in half for a 3.14-meter-long sheet.
