What does “gallery wrapped” mean? Gallery wrap is a method of stretching an artist’s canvas so that the canvas wraps around wooden bars and is then secured to the back of the wooden bar frame. People do see the sides of your unframed canvases so to me it’s important that they look nice. I like to color the sides of the canvas to make it appear as thought they are an extension of the image on the front. To me this is more interesting to look at than the usual white or solid color sides of a canvas. In my opinion, it’s also far better for the art print maker to take the time to add additional colors on the sides rather than merely wrap part of the original image over the sides as some art print providers do: If you stretch the front image over the sides then you have sliced off part of what got painted!
