"The Swimming Mop" 11" x 14" - Mixed media on Yupo. You may be asking...what is Yupo? It is a polypropylene plastic sheet that does not absorb water or water media paints. It sits on the surface. If I wanted to I could wipe the entire sheet clean with a wet cloth. It was fun to swirl paint on this surface. This is a very abstract rendition of a muskie fly I received from Brad at the show. Allot of fun but I will need to experiment more with this type of surface.
