I gave myself a little treat with some ArtGraf charcoal putty. I could never work with charcoal before because of how it felt; but this.... this stuff is fabulous! Smooth as silk! can mold to any size or shape to get the results you want. Blend it, wet it... one of the best feelings in the world. Super satisfying. I love using it on wet paper, or on dry and then wetting as desired.
So... yeah, I super recommend this stuff! ArtGraf charcoal putty.
