Rattlesnake: Tanning

I've been in Colorado less than two weeks and I'm already tanning dead animals on my front porch. Life is good. I am new at this. Truth be told, I'm a complete rookie, but nobody else stepped up to the plate, and wasting this opportunity isn't an option in my book.
This is the same rattler that we ate the other day. The job of tanning the skin fell on me, since I don't have a job or school to contend with. I'm thankful for the work and the learning experience.
After doing a little Google research, I determined that an equal part mixture of glycerin and rubbing alcohol should do the trick. Most of the instructions I found called for the skin to be split along the belly, but Seth was sure this wasn't necessary.
After mixing the glycerin and alcohol, and tying a hankie around my nose, I poured some of the mixture into the inner part of the skin. I let this spread throughout the length of the skin and gently rubbed it up and down the cavity. I hope this coats the inside of the skin enough for curing.
Next I tacked the skin, backside down, to a long board, making sure the tacks were spaced no more than one inch apart. My instructions said not to stretch the skin as this will cause it to rip when it dries.
After tacking the skin to the board along both sides, I used a small paint brush to apply the tanning mixture to the underside of the skin. I applied this liberally as it seemed to keep flies at bay.
I let this sit overnight on my front porch. I worried about animals possibly tampering with it, so I left my front door open, with the screen shut, thinking the dogs would alert me to any unwanted scavengers.
This morning I awoke and all was well. The skin dried a little, but nothing seemed to have fed on it. I untacked the skin, flipped it so the belly side lay on the board, reapplied my tacks and added another liberal coat of the glycerin/alcohol mixture.
I need to let this dry until this evening when I will untack it and lay it flat between two boards, coated in paper towels. Updates will follow.
