Hi all, I'm learning full Old Pochmann, (edges and corners), and watched Zane's tutorial (http://www.youtube.com/watch?v=idRv29MhQ74) on how to do it. But I'm still confused about flipped edges. I mean, in his tutorial, he briefly says that you shoot to both stickers. I get that part, but what I don't understand HOW you identify those flipped edges. He just says "look at this flipped edge". So could someone help me out in identifying? Thanks.
