Okay, I am venturing from lettering here, but this is way too much fun to do! My son and I took an acrylic art class two weekends ago. I took a picture of my canvas and then made it into a cell phone cover using Vistaprint. It is really easy, and it is fun to have my artwork in hand all day!
I took a picture of his finished piece and made him a cover for Father's Day. If you have patience, you can wait for Vistaprint to put this on sale.
Note: If you are thinking of doing this with an image, make sure that the image is one that is either a long landscape or a tall portrait.
