Update:
Initial thoughts, interesting and cool, but far from no-mess. Maybe I need to adjust my applying technique, but I ended up with some clumps that would fall off into my mat and the floor surrounding me. I think I may have applied too generously leading to the clumping, so I'm gonna try with a lighter layer and see if that fixes the issue.
Really cool though, if I can get it to apply evenly and not too heavily, I think it's pretty neat.
