Thanks again for all your input!
BellaBoo, the fabric I had that bled on my project was bought 8 or 9 years ago in Canada, and I didn't finish the quilt until last December, and now live in the UK. The other jelly roll was bought from an online quilt shop that also sold me a bunch of other fabrics of very high quality, and none of them bled. The bleeding fabric was batiks though, and only the darker ones bled a lot.
Watterstide, that is so very kind of you. :D I will look for the Vanish or other brands that others suggested and let you know if I find it, but thanks again for your offer!
Quilter7x thank you for that link! I did see it nad will be looking out for Shout.
Also thanks for the info on vinegar and dyes, I had a feeling the vinegar wasn't helping too much, but now I know why.
I guess I'll stick to Moda jelly rolls from now on. Anyone know about Kaffe Fassett fabrics?
