I have brain tanned a few hides over the years. I am by no means a expert by any stretch of the imagination. Last year i found this site with a slightly different method it seems to be a little easier to me. It worked out well dor me so i thought you guys might like it.
The bigest difference is the pre-smoke before braining and that the brains are mixed in water so it soaks in well without trying to rub in a even coat. Let me know what you think.
