I am trying to simulate the look and feel of finger painting done on paper. As you know, genuine finger paints are made from poor quality pigments and are not lightfast. I need to use high quality pigments, but in a mixture which has the same relative viscosity of finger-paint, the same look of finger paint, and with an extended drying time to allow for the manipulation before setting.
You may be able to do a loose technique with Acrylic Glazing Liquid mixed with the Fluid or Heavy Body acrylics right onto the paper as well, but the monoprinting method may look more natural like finger-painting.
