I've only tried painting with a palette knife a couple of times so I was thrilled to find this post, Palette Knife Painting Tips on Lori McNee's blog, Fine Art Tips. The article was written by Jonathan Van Brunt. Here's a few tips that I found especially helpful:
- There is a purity of color that can be achieved when painting with a knife that is very different than with a brush.
- Try the tapered palette knife, which is strong yet flexible. It allows you to mix the paint thoroughly before applying.
- The ultimate benefit of painting with a knife is the ease from which you can change colors....The palette knife is simply wiped clean for each color with a good thick rag. This allows more time to be spent on the painting and less on the preparation.
