This 48” BEST lightweight stretcher bar is great for smaller works of art and made out of white pine. White pine is a sustainable wood that works great for lightweight stretcher bars because it is plentiful in thin small strips of wood. They are durable and will last for a long time with the proper care, and when combined with cross braces they can create very stable canvases. A good choice for veteran artists who want a cost effective option for their smaller works of art. Cut 1/8” shorter than the measurement shown in order to fit in a frame.
