I want to try tanning a deer hide. Deer season (gun) starts Saturday. My plan is to skin it right away before it freezes. From the many youtube videos I've watched, the method I think I'll try is where you:
1. Flesh out the inner side of the hide while stretched on a frame
2. Let the hide dry for a bit
3. Scrape the hair and dermis off the fur side while still on the frame
4. Cut the hide (now "rawhide") off the frame
5. Mix up a brain/water solution
6. Soak the hide
7. Wring the liquid out of the hide
8. Repeat steps 5 and 6 about 15 times
9. Stretch the hide as it dries the last time
10. Smoke it
My issue is that I'm assuming it will be below freezing here during the process. The missus won't let me do this in the kitchen

I think I need to do steps 1, 2 and 3 while the hide is still fresh. I think steps 6 through 9 will be hard to do if it's freezing and cloudy.
Can I stop after it's cut off the frame and store it till spring? Or maybe after step 2? Is it shelf stable at either of those points?
I know you can freeze a fresh hide but I don't have the freezer space to do that unless it's really the only way.
Thanks!
