Gallbladder trophy mount

Trophy-mounted gallbladder

My friend has had gallstones, but with no insurance, just suffered through them for the last year. She just had her gallbladder taken out at the ER and is, happily, doing fine. But for all the trouble it has given her, I decided to stuff and mount the little sucker like a trophy animal!

I even included a few pebbles in the stuffing so you can feel the gallstones!

Construction was easy and took a few hours. I had the felt and thread in my hobby drawer; the pattern was free-form (trust me, I have no skill). I used cut up-scraps for the stuffing, and, of course, rocks from the yard. It's sealed with a few scarps of yarn. The wood plaque was bought at a hobby store for $1 and sanded/stained with leftovers found at my local hackerspace. Someone had donated excess brass sheet stock, which I used in a minimill to engrave the plaque. I decided to use a magnet to mount it to the plaque so that the plushie can also live on her fridge. Our space didn't have extra magnets, and I didn't find any suitable ones in a motor I took apart -- so I had to buy a six-pack at the store and am donating the extras for the next person.
