I don't know how anybody else holds there stamps, never really paid attention. However I hold mine with four fingers. The thumb, index and middle are on opposite sides then my ring finger on the same side as thumb but with the nail touching wifh just enough pressure to hold the stamp steady. Then just use the weight of my hand to hold the leather. On really small peices I hold my hand like someone left handed when writing. As far as the keeping it from stretching I use old x-ray film I cut down to what ever size then rubber cement it. The only down side is I can't do it if I'm not going to line it, the rubber cement leaves it too tacky. For that I just use packing tape with no problem. However when I run low on packing tape I'm going to use Chiefs idea because that would be a lot easier on bigger pieces.
