I have seen knitted ovaries and plush organs, but it’s rare you see squishy (fabric) brains…
I featured this museum on the site several years ago. It doesn’t look like they’ve added much since then, but always interesting.
The Museum of Scientifically Accurate Fabric Brain Art bills itself as “the world’s largest collection of anatomically correct fabric brain art.”
h/t to the Scientific Illustration for the Research Scientist page on Facebook, so thanks for the reminder, but check out the museum’s website for more.
