O.K. I'm a little confused. I know we wash them, then iron them, then do the iron transfer and I too will do the vinegar was after the transfer is done, but karajeboo you mentioned your MIL ironed the shirt. If they come out wrinkled after the vinegar wash does that mean they can't be ironed - I mean ironing the shirt except the part with the transer?[/QUOTE}
If you are worried about the shirt wrinkling when it comes out of the dryer, add a towel or two to the dryer to help toss it around a little, speed drying and keep it from wrinkling quite so bad. You can iron any part that does not have the image on it, just use the lowest setting that will do the job. I have used the backing from another iron on to press over a shirt that needed it, placed the backing on it just like it was originally and pressed, again lowest setting that will do the job. In this case you need to be very very careful that you don't pull up the image you ironed on to your shirt.
As far as brand, I have used many different brands, I know Avery was one of the first. My favorite one, I can't remember the brand name, but it says "Oops Proof" on it and has a money-back guarantee on it. It used to come with a Hanes T-Shirt, if I remember right.
I am actually trying a new brand this time. It's from
www.printonit.com. I will let everyone know how they turn out after I get them done.
