I say that all of my paintings are painted on gallery-wrapped canvas, but what the heck is that, you ask?
Gallery-wrapped canvas is canvas that is wrapped around wooden stretcher bars and stapled to the back. It doesn’t have any visible staples holding the canvas to the stretcher bars, thus giving a finished look so that the painting can be hung unframed (you can also frame it, if you like!)
See how the canvas goes around the wooden frame, without any visible staples? That is gallery-wrapped canvas!
