In the future I plan on maybe making a fullsuit of a fursona (a different one then my avatar) that happens to have glow-in-the-dark markings. And, I have been searching all over the internet to see if fur like that was even a thing, and I haven't been able to find anything. Plus im trying to avoid the LED option as much as possible, cause, well LED's and all their wires and battery packs would just confuse me. X3 so I was just wondering, is glow-in-the-dark faux fur even a thing?
You could always airbrush glow in the dark paint onto the fur, that's how I'm planning on handling my R3N3G4D3 fursona when I finally have the time, money, and skill to make him in a few years.. although I'll be doing my therioside suits first.
One thing people always forget about science: science never demands a rational explanation for anything. To science anything is possible... including magic... especially magic.
