We find that canvas adds a beautiful texture and a classic feel to our images. It also completely
eliminates the need for glare control, because no glass is used to frame it. (All of our canvas
pieces are treated with an appropriate UV light blocker.) Being glass-free has the additional
benefit of making the piece lighter in weight, and therefore able to be hung in places where a heavy
frame might be too much for the supporting structures.
That is by and large a matter of personal preference. Frames do add a degree of structural support
and protection for the canvas, especially on the larger sizes, but they certainly are not
required for the successful display of your canvas.
