I just want to reinforce what Cheryl said on an earlier page. You need to buy Synthrapol. You can order a 4 oz. bottle from JoAnn's for $2.79.
The quilt shop owner sounds bossy but it may not be her fault. I have had expensive name-brand fabrics run and I routinely presoak my fabrics in Retayne to set any excess dye. My basement often looks like an Easter egg dying center withall the excess dye that comes out. Retayne is for commercially-dyed fabrics; Synthrapol will serve the same function for hand-dyes. But definitely try the Synthrapol soak to try to restore your quilt.Don't feel too badly. I remember on one "Simply Quilts" show, Alex Anderson,
a quilting expert, revealed that it had happened to her.
Anyway - don't go to a store. Use Google to search for the cheapest prices on Retayne and Synthrapol. I hope the shipping isn't exorbitant. When I bought mine, the cheapest prices were at "Soft Expressions". However, Australia has a robust quilting industry and should sell these very necessary products. I never found that the cold water/vinegar solution was as effective in fabrics that were determined to run, like teals, purples, reds, etc.
If the Synthrapol doesn't work, I would e-mail Alex Anderson and ask for advice. Any quilter would be sympathetic with your plight....
Best of luck. - Judy
