I distinguish my canvases by supplying them at very large scale framed in impressive, 3 to 5 inch wide frames that would make Peter Lik envious. Sofa-sized through boardroom-size, that's where the action is.
I have a shop system that makes those easy to produce, the cost to me is not dramatically more than a set of stretcher bars. The canvases are mounted, which is also a very efficient operation. For not much more time and effort, for a given price calculation I get a price point not too far above wraps, with much higher perceived value.
Large scale framing is a tough nut to crack and gives you a significant competitive edge. Customers almost universally place a very high value on large scale framing (say 30 x 60 on up) and do not classify it in the "we can get that for zip down at Costco" category. It's still something special much like large wraps were 5 years ago. And the notion that professional framing is wildly expensive lives on, I milk it for all it's worth.
