Can't speak too directly, but is Rayon one of the suggested fabrics? I know that there are dyes and processes that work better on Rayon than Cotton. I'm pretty darn comfortable with Rayon in quilting. I figure (among other tests) if I can do a burn test and not be certain if something is rayon or cotton, it passes that way.
I have an older quilt that was made from scraps, including a patch from a favorite dress that met up with a bad ink pen. I know the dress was 100% rayon, and some 30 years later and most of the quilt is in tatters (is in the dog bed) the rayon is actually holding up with the cottons, without either being noticeably impervious to atom bombs or fraying.
Rayon is a cellulose fiber, as opposed to full polyesters which are basically petroleum/synthetically based.
