Thanks Brian. Great information for a newbie. Hadn't even thought about distance from the edge and I can see where it would matter. Trouble is they're very expensive and you don't see used ones very often in the UK. However, even though I've never sold a single piece of leather in my life YET, I've always believed in having the right tools for the job. Another couple of cliches, buy once cry once and start the way you mean to go on. I can feel my budget stretching by the minute. Any cheaper suggestions welcome.
