If you have some old acrylic paints that you don't want to throw out like I did, try pallet painting techniques. My paint was thick, dry and clumpy but still, I think it created some cool effects and design! I call it "organized chaos".
What's your favourite style of painting? Abstract, Conceptual, Photorealism, Impressionism, Hyperrealism, Minimalism, Fauvism or Futurism?
