Huh! I think using the folding method makes the paper towel seem much more absorbant than without the folding!
I just gave this a try using one of the perferated paper towels in my kitchen. They're the small sheets, too, so I was skeptical. But my hands feel completely dry! (I also did the 12 shakes!)
I'll definitely use this at work, because I often took two paper towels since I felt like just one didn't make my hands very dry. I bet if I do the fold, it will make a big difference!
