if you can find good quality images of what you like (perhaps purcahsed from a photo stock place) you can arrange to get them printed on canvas through places like fabness, often scoopon have specials for canves prints. I got a photo of our children printed on canvas 1m by 0.5m for $49.95. They also had three sqaure canvas's for the same price the other week.

What size were you wanting?

Good luck

ETA a lot of sellers on Etsy are happy to make custom sizes/designs if you ask, is that a possibility if the prices aren't too steep?
