Acrylic Painting.
I discovered the medium of acrylic painting technique only in 2012. It was a big change after so many years of watercolor painting, but I soon discovered the advantages. I am particularly enthusiastic about pastose acrylic painting, which makes the painted pictures almost three-dimensional. A version of this medium which I like to use is painting with painting knives.
Other subcategories of acrylic painting that I sometimes use are fluid art or pouring, painting with acrylic ink and glaze painting with acrylics.
Here is a small selection of acrylic paintings but you can find more in the various blog posts and the inventory.
