A 10” BEST lightweight stretcher bar which is constructed from white pine. Lightweight bars are a good choice for smaller paintings. They are a great cost saver and a perfect choice for college students, new artists and for small canvases. Lightweight bars are good for light canvases as well, and you should not use them for large paintings. Keep in mind that BEST stretcher bars are cut 1/8” shorter than the listed measurement to ensure that the frame with the canvas will fit into a picture frame, because the canvas can add more width to the frame once it is stretched.
