Along the lines of the old carpenter's adage "Measure twice, cut once"...before you commit that last bit of blade pressure to a fresh hide...make sure ou know what you are doing.
In a classic case of Coulda, Woulda, Shoulda, but Didn't
I screwed up my grizzly hide this fall when taking out the feet...I cut out the toe pads to make it easier to get to the knuckle joints. I assumed (I know, I know, I know) that the pads on mounts were artificial. So, in my confident stupidity, I rendered my hide un-rugable because without the pads the claws won't lay right. The taxidermist was up front about it from the start. I now have a tanned hide to remind me of my error.
Yes, I was tired
Yes, I was cold
Yes, I thought I knew what I was doing
If you are going on a hunt for an animal new to you and where you plan to have a taxidermy bill afterwards...talk to your taxidermist BEFORE going and get their advice and follow it. Take pictures if your taxidermist has similar work in the shop while you're there. Maybe check out Youtube (virtually everything under the sun has a "How To" on Youtube)
If you're ever unsure? Don't make the cut. Suck up the extra pack weight.
