I've seen it done, but I was young, and wasn't watching that close. I knew somebody else who could do it more recently but he wouldn't let anyone watch... anybody out there able to do this? You make an outside piece and then literally turn it inside out. (and using glass shears and cutting it doesn't count cuz it leaves a big "scar" where you join it back together) The way I saw it done involved turning the tube inside out like a sock, so we called it a sock flip, but I don't think thats the real name. Anybody even know the real name for this technique?
