I use the liners only for painting grass. I mix 3 or 4 different shades of green (my favorite is yellow & black in stead of yellow & blue) and I heavily liquidize the seperate mixes with a lot of medium.
Then, with quick movements, I strike every single blade on the canvas.
No, this time I don't count them.
This is a part of the painting with the Gooseberries, a couple of entries below.
