So I have a question, my brothers friend is bringing me a cougar hide to make into a rug today. He states it has been frozen almost a year, my concern lies with hair slippage and how he stored it. Knowing him it wasn't properly fleshed and will need the lips and such split. My question is how long is it ok to leave out to thaw... I will not be able to work on it until tomorrow and he is driving 4 hours to drop it off, I wasn't sure if the fridge would be the best bet until then or to let it naturally thaw in the basement. But I am just worried about it beginning to rot or hair falling out; usually I will flesh right after skinning but him keeping it in the freezer and not being able to work on it immediately kind of puts me at a stand still.. any advise is appreciated.
