Hello, I recently purchased this frame and because of the unusual size I had my hubby cut me a panel for it. I needed the canvas to measure 6" x 18" and that sure isn't a standard size. I originally thought maybe a landscape or a row of pears but then I decided to turn it vertically and paint Hollyhocks. This is oil with some nice texture in there. I have an art in the garden event in August so I think flower paintings should do well there?
