Winter Trees is my new favorite.
I painted this on a piece of MDF plywood and framed out the back side with 1 x 2. I didn't want to buy a gallon of gesso so I used Kilz primer instead and it seemed to work fine. I spent far less money using this medium than buying a canvas this size.
Because of the size of this piece I used a ton of paint but it was worth it.
I also included a picture of me holding the picture so that you can get a sense of scale.Winter Trees
