Most of the time, I use watercolor or pastel and alcohol as an underpainting but I’d like to experiment and play around with other mediums. I just bought a small set of Cretacolor Woodless Aquarelle Pencils. I’m going to play with them using as an underpainting. Also have some new Inktense Derwert pencils I want to try. The darker Inktense Derwert worked ok but I didn’t find that I like it any better than pastel and alcohol or watercolor.
