check out this awesome work by Margie Livingston
jealous curator, a great blog.
All of these are made from layers and layers of acrylic paint......I'm guessing she's using some mediums as well.
We carry a few lines of acrylic: Golden, Liquitex, True Color, and Galleria.
Come in and check out our large selection of Golden paints and mediums and see what you can build with layers.
If you need some help to get started check out this book New Acylics.
