I have used the purchased sheets and made my own-I have had great luck. I usually make my printed sheets well in advance so I can let them totally dry overnight-then rinse until the water runs clear with cold water-then allow them to dry overnight before ironing in the print. Only once did I have some prints completely wash out and I had used my HP printer at work, but I have used an HP and Dell printer at home with excellent results...do not know what made the difference that time except that maybe I should not have been making copies at work for personal use-HA!!!
