I have printed a few out as 8x8 because if I put it on an 8x10 canvas, I can send it to Walgreen's or WalMart fairly inexpensively. I'd recommend getting it printed in a smaller version before investing in a larger version because the 12 x 12 format can be so expensive to print! Most of them have turned out close to what I expected, but the colors were off in a few. One of them was of some cousins at a reunion and it turned out well enough to do duplicate prints for each of the cousins.
although there are still occasions for which I would print them, most of them will go on my computer as screensaves or on my digital picture frame at the office for my enjoyment as they rotate.
