A while ago I did started out trying my luck at making fish skin leather (specifically salmon skin leather) and after a while I decided to do a blog about it. Latterly I have followed that up with a Youtube video that I will add to the blog as both have info, findings, hits, misses, poops and gaffaws that the other doesn't.

If anyone is wiser than I in this field I'd be happy to hear from them.
