I am so very honored to be a part of a local artist group that hosts a huge pop up show in our community every year, and as a part of that show we do a collaboration piece together. We each take a piece of the image and use the materials of our choice and our own interpretation of the colors and lines.  I am always amazed at how well it comes together.
The image on the left is from our 2016 project that currently hangs in the Campbell County Courthouse.
The first panel is acrylic, the second is paper collage, third is oil paint, fourth is enamel, the fifth is acrylic and nail polish and the sixth is glass mosaic. 
Of course, these are a must see in person!
