Stretcher bars are essential items for artists who want to create their own stretched canvases. However, there are many other names for this type of bar that can be used interchangeably. For example, stretcher frames, canvas stretchers, strainers, and canvas bars are all synonyms for the term stretcher bar. While the name may vary depending on the individual or the location, the function remains the same: to create a sturdy and stable frame that will hold the canvas tight and prevent any sagging or warping. Whichever term is used, the stretcher bar remains an essential tool for artists and craftsmen alike.
