I am sorry that is a lot of hard work to have that happen.
I was going to buy this green fabric - but the owner told me it just kept bleeding not to purchase that fabric... The store owner sounds like she knew this also....besides the synthropol there is a resytan (sp) which stops fabric from bleeding. I have some old red table clothes that still bleed a little red.... I think I heard to use vingar... You might what to e-mail the darma company they sell fabric dyes and dyes setters.... They may be able to help - I would not dry the quilt because I think that sets in the dyes..Hope this helps
