At one time I did use Bubble JetSet to treat my own fabric and then ironed it to freezer paper, but my printer does not handle that well - it often jammed and I have a scar on the back of my hand to prove how hard it was to remove all the bits and pieces from inside the printer!! For that reason I prefer to buy pre-treated and have always used Printed Treasures brand (use your 40% or 50% coupons from JoAnn's). The inexpensive HP printer I have now does a pretty good job but I would like a printer that will allow me to enlarge or reduce designs. If anyone has used another brand of pre-treated fabric, I would be interested to know more about it. The Printed Treasures sometimes gives me a hard time when I try to remove the paper from the back.
