Hello, I am looking for advice regarding washing of Iron on Applications. I purchased the Avery product and have been doing some iron on for white tee shirts. The instructions say to wash after completing the process. I washed a few in Wisk and the applications seem to fade a little bit. Not bad but there is some fading. Washed in Cold water and dried on light fabric setting. I also used fabric softener - the kind you put in the ball and drop it in the washing machine. What kind of detergent do you use? Any advice on how to reduce fading? Thanks folks.
