Have any of you ever experiment with DIY art supplies? Stuff you've found around the house or even more unorthodox sources?

The cyst above my asscrack finally bust open after I sat down too hard. It was there for a couple months and was full of puss and blood. I've managed to save up around two shot glasses full of it. There is obviously the cream color, but there are also streaks of crimson from the blood. I think if I squish some of the curds of puss I could use the paste for a unique texture in my works.

I realize this is a strange idea but art is meant to push the boundaries of sanity and imagination through innovation.
