To be fair to Devonia, they rather had the sudden massive increase in custom thrust upon them when Fenland closed. They will have had to find a way to accommodate the increase without disappointing customers, so I suppose that takes time.
Fenland did a wonderful job and were very knowledgeable.
We had some Jacob skins done by Nicki Port a good few years ago - the skins were quite thick and the colours ran/faded, so the dark spots merged with the white and became brown, even though the skins were not exposed to the sun. That was in her early days, so I expect things have improved since then. She also did a deerskin for us and my OH had to go to the workshop whilst she finished it - but I don't blame her at all as it was a horrible, heavy job to do. I tried to persuade her to do some moleskins for me (we had LOTS) but she wasn't game

I don't know if this is still her method, but back then she used mimosa as part of the tanning method - which has got to be better than chrome
