So, this is a thing that actually happened. It’s canon! (3×19, “LSD”)
This entry defines “quick and dirty” but hopefully demonstrates the amazing versatility of the Sketch Club “Vector fill” tool when used as a brush set to lighter opacity and gradient fill. It is best not to chicken out and try to smudge/blend the vector shapes. (um, a bit guilty here.) If you’re going to do something sketchy, commit to the tool you’re using!
