What I always recommend is washing in Synthrapol in *lots* of hot water. If you don't have a top-loading washing machine at home, take the quilt to a laundromat and use their largest front-loader. Synthrapol suspends unset dye particles in water so they can be rinsed away, but you need a lot of water to dilute the dye. Depending on how much dye is released into the water, you may need to wash more than once with Synthrapol. Do not let damp fabrics lie against each other (dye can transfer via "crocking" as well); toss quilt immediately into dryer. Google Synthrapol for more information, or check old threads on this board.
