A piece I did inspired by Joanne Fink's Zenspirations. If you like doodlish drawings, look her up. You'll sure be inspired.
But I did this on fun foam! Did you know you can paint on fun foam (or craft foam, it's also called)? And it's amazing to work on, especially with acrylics, since they dry much slower than normal.
For this one I used acrylics, Tombow markers, gel pens and Uni ink pens. Check the post with more pics of this if you like.
