I'm very new to leather work - have yet to even try to sell anything - mostly because I consider most of my work to still be in the 'He's Still Learning' category, but I got to agree on the quality workmanship, or lack there of, that I see being sold around here and at what I would consider to be more than a premium price!
We have several local 'weekend markets' where local craftsman can show/sell their wares... One in particular sells "custom, one-off, hand made knives' with a matching "one-off Leather Sheaths"... and he asks what I would consider a very high price... His 'one-off sheaths' are garbage... poor stitching, edges not finished, poor dying work - you name it and it's wrong... His knives are ok, and if he were to put as much care into his sheaths as he does on his knives they might actually be worth what he's asking.
There is also a new store in the area and while they have a number of interesting items and a small supply of hardware and leather - the Quality Control on their hand-made items leaves a LOT to be desired. Again, it is the raw, unfinished edges, and VERY poor stitching - most of which is machine done.
