I used liquid frisket extensively for the twigs and branches of the background and painstakingly spattered and hand-painted frisket snowflakes across the whole piece before laying in loose background and body layers.
The paper, being sized to resist pilling and handle frisket, does not lift at all and paint won’t reactivate after drying, so once color is down it indelibly stains. Working within those constraints and making use of great glazing characteristics I was able to paint most of the tiger wet-on-wet and wet-on dry, to get the soft bleeding fur, seen through a snow storm effect.
