I haven't used this product, but don't imagine it would be any better than using starch. There is also a video on using it on fabric to print photos with a printer. However, unless you buy fabric treated for printing on (and you may not need it stiffened any more for that ) the picture will wash out.
You will need to pre-treat your fabric with Bubble-Jet-Set first, and when that is dry, then use the Terial Magic. I don't think the lady in the video mentioned that, perhaps she doesn't know about it.
