My friend and I just finished tanning a bear fur and it went pretty well. It came out mostly soft and the fur is really nice. We did it using lecithin, no nasty chemicals, lecithin smoke and salt. I’ll post pics tomorrow… the only thing that wasn’t quite right was there was 2 places where the grain and fur were coming off, I think this is called grain splitting? It was just in 2 small areas. What causes this ? I just found another super fresh roadkill bear and am going to tan it for my dad and don’t want the whole thing to have that grain splitting problem. So any idea on what causes it?
