I've been using Deer Hunter's & Trappers hide tanning formula to learn how to tan. However, after breaking the hides (squirrels) as they dry (hides completely white), they still end up as stiff as a board. What am I doing wrong? I want to tan hides so that they are really soft and flexible (fur on). Here's a more in-depth description of what I did... 1) Skinned and washed with dishsoap 2) Salted and let dry for 2-3 days 3) Placed into Citric Acid pickle. Maintained at a PH of 1.5. (1lb of salt for each gallon of water) 4) Removed from pickle after 2-3 days. Finished fleshing by hand with spoon. (able to remove 80-90% of the membrane.) 5) Returned to pickle for several days until ready to tan. 6) Removed from pickle and left to sit in room temp tap water for 15-20 min (to neutralize) 7) Warmed bottle of tanning solution in bowl with hot water. 8) Dried skin until damp and applied tanning solution to skin side. (perhaps a bit liberally). 9) Noticed tanning solution in fur and was worried it wouldn't come out, so after letting the tanning solution sit skin to skin side overnight to soak in, I rewashed the hide in soap and water to clean solution out of fur. 10) Worried that tanning solution would have been too diluted by the washing, I applied another coat to the skin side (very carefully this time to not get it on the fur). 11) Let sit for another overnight and worked to break the skin until white. 12) Came back later to find that even after breaking, when fully dry the hide has a thick paper-like consistency and is stiff as a board. 13) When rehydrated with water (sponged until slightly damp) the skin quickly softens up, but even after more working while it is damp again, it goes back to being quite hard (though not as much as before) What are your thoughts about what I should do next time to make the hide softer as a finished product?
