My Muffet (from Undertale) fursuit/cosplay! Extra arms have fully poseable armatures (jncluding the fingers), padded and covered in minky, and attached to a corset rig. Head is built of plastic canvas and foam with three-dimensional buckram eyes (there is a fan behind the middle one). There's a zipper down the back of the head to keep the neck small. The minky fabric I used btw is called "minky dot" and comes with embossed bumps all over it, which I was able to press out. So glad that worked as a fuzzy lavender fabric was hard to find! I had actually bought some crushed velvet but I'm so glad I didn't have to use that. And I didn't want to use fleece, though I could have.
I used a pattern to help me make the blouse but had to make the jumper with the pumpkin-pants type shorts out of my own head and it was a paaaaaiiiiin, lol. I totally see why no one else seems to have a Muffet cosplay yet. (I haven't seen one? Let me know if you know of one, even if it was made after I made mine, I'd love to see it.)
