In response to the tile on a tile challenge from the Diva, I decided to do it with color. I pulled out my favorite Tombow marker shades and colored my center square with a watercolor technique. When it was totally dry I used a white pen for my center tile. The black pen came next and when I needed more to connect the tiles I added a little bit of the Tombow's color with a fine tip brush. You'll see I got a few color bleeds here and there, but I don't mind too much. They add to the character. This was fun!
