Then I've looked at my palette and have seen some dry used colors mingled together, that has put an idea in my mind, why not look for some patterns of paints flowing into each other? so instead of cleaning my palette I've taken a sample of yupo I had around and thrown Lamp Black and French Ultramarine Blue all around hoping to get some patterns I can use in the visit cards.
Lesson learned: Yupo is an interesting animal... worths giving it a try.
