What does gallery wrapped canvas mean?

A "gallery-wrapped" canvas means that the sides of the canvas are visible when hung and the painting or printed image extends around the sides.  These typically use a deeper stretcher frame to make this a design feature.  Our 1-½"-deep Gallery stretcher bars are designed as an economical option for this purpose and are suitable for frames 6-60".  Larger frames would use one of our heavy duty frame options.
