The gallbladder. Such a tiny little thing who can cause such big problems when it is unhappy. My own less than pleasant run in with a rather cranky gallbladder inspired me to crochet one so I had something physical to remind me of that experience. Plus, this one will not rot like the one they might have taken out of you. This gallbladder is crocheted in cotton yarn, stuffed with polyfill and has a few glass beads in it to replicate the stones that may or may not have sent your gallbladder into a pain inducing tizzy. It is about 5 inches long and 1.5 inches on the widest part. It is made in a smoke free and pet friendly (woof...no meow) home. Please send me a convo if you have any questions and have a great day!
