PMSL, he knows how I feel. He even gives the same advice to people... Occasionally people we know (or who know people we know) think they should book him for their weddings, but they can't see why his photography is more expensive. He tells them that if they can't see why, they should book someone else
What I mean is, you can get great quality photography with great quality canvasses from a professional studio if you haven't got a good enough quality photograph to do your own decent-looking canvas with.
The other thing that looks great for enlargements are acrylic prints. They're a very different look to the canvas, but look brilliant.
