Not so much a tip as experience. I printed a picture onto a sheet of DigiEZ Fine Art Pure Cotton Canvas.
I followed the instructions and precautions closely and the result was perfect. I really didn't have to do anything different from normal printing.

I had no hiccups or trouble at all.
I don't think I want to use that sort of fabric for quilt blocks because it's too stiff but for totes or pictures to frame it's perfect.

If I get time today, I'm going to try some sized artists canvas. As Alma says it is very stiff, but I think it has potential for greetings cards.
