Hello, I "married into farming" and recently slaughtered my prized belted galloway cow. I couldn't let the hide go to waste, but sadly the decision was made so quick I didn't have time to get all the tools I needed and I've just been doing the best I could with the time given. I'm trying to turn the hide into a rug... I fleshed, salted, used a product called "Deer Hunter's & Trapper's Hide Tanning Formula." Followed almost all of the directions... Here's where I went wrong and where I am needing help! Let on tanning solution for 12-16 hours while the skin was fold in on itself. I had my husband "open the hide" to dry, but I forgot to lay it flat when I got home... So it molded to the shape that it was on. Most of it is flat, but I have two spots that are large and bubbled. Do I go on with the process and try to soften the hide and hope it will lay flat-ish... Or do I need to get that large bubble "fixed" to make it flat. I did try stretching, but it's pretty dry now and I wasn't sure if rehydrating would help? Thanks in advance for any help or advice!!!
