IMHO, cyanotype on fabrics is fine if you want to use it for decorations -
I have a beautiful hanging quilt by Melanie Walker with clouds printed in
cyanotype. For wearables, Inko Dye works so much better because it stands
repeated washing without danger of fading.
Inko Dye does not work well on paper mainly because it is almost impossible
to get the unused dye out by soaking alone, and I doubt that any paper can
be survive a washer without turning into pulp.
In my experience, some Inko Dye colors remain usable for decades when kept
in their original bottles, while others can't be used for photographic
printing even when fresh. The way to tell is by the color - good ones
should be colorless before it's coated and exposed. Of course for the folks
who produce the stuff there are no bad ones - they market it as a heat/
light setting dye, not a photo printing emulsion.
