Re: Home made dubbing
I don't know if I'd do it for an entire hide, but a few years ago I picked up a dubbing rake...it's a small tool that looks exactly like what you'd imagine for the dental tool version of a garden rake.
It's used to scrape a hide, and pull up a mixture of longer guard hairs as well as the soft, dense underfur. I use it on a few patches I have of things like mink, muskrat, nutria, beaver, and opossum and it works great.
A little dubbing goes a long way, so you may want to consider tracking down a dubbing rake for yourself and attacking various areas of your pelt and pull a little here and there until you have enough to fill a small bag like you'd get in the store.
