My brother and I trap them sometimes, so I get my tails from the source. Working them from the animal into grip leather is a pain in the butt. It would be easier, and probably cheaper, to buy them but that's not my style. Besides, the fur is useful and meat is delicious and it's just plain old fun trapping them. It isn't stretchy like the deer leather I usually use, so is better used on straight grips or those with a little less contour. That reminds me, I have some beaver and turtle I need to tan soon.
