So I just started with preserving my first squirrel tail (bone out). I've started with this (see picture) as you can see, the end came off while cutting down the tail. I have salted it and it is sitting right now. I've read about using borax, which is what I plan on doing. Any advice?
Sounds like you are on the right track, I would slope it on a 45 degree angle so any juices that comes out of it drains.Change the salt tomorrow. The borax is a bug deterent as long as you keep it dry it should last a long time. Welcome to the site.
I have always just cut them off and laid them flat until dry. I have tails that are 10+ years old that still have the hair. Seems like a lot of work for a squirrel tail given that my method has worked. But then again, maybe I just got lucky!
