I would not totally agree with the home tanning concepts as posted. Yes it may be cheaper than paying a professional and quicker than a commercial tannery and yes you will end up with a very stiff/ridged rug.
But a commercial tan offers better stretch,thinner leather, consistence thickness of leather, and generally cleaner fur. Why are these important to a good mount? Thinner and consistence leather thickness allow sewing to be much easier and sewing seams such as in the arm pit will match much nicer. Also sewing your felt boarder and backing on the pelt will be more consistent and much easier. Of coarse you could use hot glue, but i would not recommend it. Commercial tanneries use cleaners in the drumming process and degrease pelts.All which give you a clean and lively hair and the hair will lay right in all the important places,such as around the eyes and ears(on a wolf rug). When the hide is thinned (shaved) properly. you'll have less chance of drumming(shrinkage) around your head, the taxidermy part of the rug.
But if your wanting to attempt tanning and rugging your first wolf for the experience. you will have fun and experience what commercial tanneries deal with on a daily basis and the time it takes to have a quality product.
