Thought I'd saved a couple of Youtube vids but can't find where! Will try and source again for you. There were by a heavily bearded man in a forest! That's all I can give you right now
If you go on youtube and key in 'tanning sheepsins' or suchlike, I'm sure, like me, it won't take long to find something useful.
Key in Xavier de la Foret. It's a five part vid clip. I found it really useful.
