Use something like Buble Jet Set and Buble Jet Rinse on your fabric. First treat your fabric with Buble Jet Set solution and after it is dry iron onto freezer paper. Or you can buy freezer sheets already cut. Trim your fabric the right size for your printer making sure you have no loose threads before printing. After printing allow to dry for at least 30 min. then rinse in Buble Jet Rinse. It will set the colors for you and not wash out.
Very sorry about your Uncle. He very much reminds me of an old friend of mine, he had a newphew named Kendall.
