you might could use mylar, I know some embroidery designs that are coming out now. do a utube search for embroidery or mylar and check it out. Mylar comes in different colors, but I think you would have to be gentle about washing any thing with mylar. I know there is a iron on vinyl. but I think that would probably be to stiff. try a sample and then wash it and see how it works. good luck let me know how it turns out for you.
