The solvent I use is "Mona Lisa Odorless Paint Thinner." You still need a good amount of CP pigment on the paper before you can use it. Experiment first on a small area, if you are not sure if the amount of pigment on your paper is enough. The nice thing with solvent is that you can work on top of it either while it's still wet, or after it has dried.
