What first started as a "oh hey, this shouldn't be too hard to make for a convention in like a month..." became a "omg what even are these tentacles?!".
I'm still working on my canister, and I need to make the suction cups and spots for the tentacles.
The tentacles are made out of PVC fabric. I designed a pattern, eyeballing the shape based on the Inkling Girl amiibo I own, and I sewed the pink half and the white half together, and stuffed some polyfill in at the bottom at the biggest part. They attach to my wig and go under my hat so that you can't see the "seam" between the wig and the tentacles.
