Start a punch down fold but don't go all the way down.
Fold in the other side the same way
fold in vertically
My thoughts- Well i actually think this fold will be as used as the "squiggle" or "S" fold, but i haven't tried it so i wouldn't know how comfortable it is to insert.
I shall call it the double punch down fold or the fish fold.
Please tell me if you have used it and how it goes. I would feel like i have made a difference ^-^
