I never thought of dry brushing water colors! Good idea.
I figured that watercolors would bleed more than markers but dry brushing makes sense, regarding how to avoid that. I had thought acrylics would be required.
Pastels work but can flake a lot and become messy.
good idea!
I use my acrylic hobby paints when I'm at home, and am using just cheap craft acrylics here, $.50 a bottle at WalMart.
