Great process, but would love to customize the BACK, too

I had a very easy time uploading my logo and customizing my tee shirt, it just arrived and looks so, so good, I can't wait to wear it at my first craft show. My only feedback and the only reason I didn't give 5 stars, is because I really wanted to put another design on the back of the shirt. Update your software to enable this and I will buy many more!
