A friend of mine had found a painting of cotton that she really liked, and wanted to know if I could try to duplicate it. Since I saw "palette knife" all over it, I jumped at the chance. This is the biggest painting I had ever done, so a good challenge was in the offering, too. 20X30!
First I painted the canvas Van Dyke brown. I then bought some acrylic paint and realized I would likely need more and bought sample sized latex paint at Home Depot much cheaper.
I put my paint on my very sophisticated palette.
