Salmon raw hide

1. I have made the tannin solution from my acorns.
   
2. I have obtained and removed the meat from a salmon skin.
   
   
   
3. I washed said skin.
   
4. I rinsed the skin.  
5. I placed it on a rack and put it in the shower to dry. 
   
6. I closed the bathroom door so the cat could not get to the skin. 
7. I discovered the bathroom door open.  
8. I removed the salmon skin from the dog's mouth. 
9. I repeated steps 3 - 6.
10. I put a fan in the bathroom.
11. I removed the rack and skin and put them in the oven - no heat -  so hubby could use the shower for its intended purpose.
    
12. I have achieved salmon rawhide!
