My 12×12 canvas seemed too small for the Jasart frame. As a result, the drill holes were set so close to the edge of the canvas that I damaged the edge of my painting. I was also disappointed that Jasart did not provide spacers. When you see the Jasart video it looks like they provided the spacers in the pack but they don't. I also bought the 18×24 inch (which I haven't used yet) but this version appears to fit the canvas more snugly. The concept is still great but the smaller size did not pass muster.
