Ladies, I DON'T USE SYNTHRAPOL. I use a product made by Ritz (I have no interest in this company, except using the product successfully) The product is a Dye Setter and it permanently sets the dye in fabrics that would otherwise BLEED. I order it from Rit Dye online. I had a white, whole-cloth quilt made as a wedding gift for my nephew -- the borders were a very vibrant red, and after testing the fabric BEFORE USE, I discovered it was a BLEEDER. I researched and found the Rit Dye Setter online, ordered it and used it as directed. One thing I've found is that if you have multiple shades from less-vibrant colors, you can mix according to directions in a "stew pot" and simmer for 20 minutes on the range. By starting with the least-vibrant color, you can graduate to the more vibrant colors, by adding an additional tablespoon of the product from the bottle. ONE CAUTION: DO NOT "SAVE" THE DYE-SETTER AND WATER MIX -- i'VE NEVER TRIED TO, BUT i SUSPECT THE MIXTURE WOULD LOSE ITS EFFECTIVENESS. If you have any questions, please send me a pm. ALSO, I take extra precautionary steps -- I ALWAYS USE A COLORCATCHER WHEN I WASH QUILTS! A bleeding fabric in a quilt is a disaster!
