To create texture with the pulling, pushing and dragging techniques, it’s imperative that your brush, the paint on your paper and your palette mixture are all the correct dampness. Here’s what to look for:
The brush must be slightly damp to the touch, the bristles on the very end should be splayed and you shouldn’t be able to squeeze any water from the brush.
The paint on the paper shouldn’t have any shine to it and you should be able to stand the painting upright on an easel without the paint running. The paper should also feel cool to the touch.
Any additional paint that you’ll be adding to the paper, such as a mixture you’ve prepared on your palette, shouldn’t be too juicy. In other words, you must maintain the same dampness of your brush, paper and paint; otherwise you’ll be creating havoc.
