Prepping to make art, from found materials

A few weeks ago, I picked up an 8×7′ piece of heavy, cotton duck canvas, painted on one side. Cut into 4 pieces. Been thinking how to use a couple old, wood window frames I found. I’ve used them as frames, before, both for paintings, and assemblages, so thought I’d try stretching a piece of canvas to the back side–using it as both stretchers and frame. The painted side, a thick coat, so couldn’t do much ‘stretching,’ but got it reasonably tight. Canvas wasn’t seized, and really soaked up the gesso. That’s a second window frame behind in the photo.
