I had this issue with a white baby quilt I had made, and I had washed the purple fabric, (about 4 times, and it still bled). Use Retayne, you can get it at most quilt stores, it works wonderfully. I also used the Bounce Color Catchers, but they just couldn't absorb all the excess dye. Once I used the Retayne one time, it never bled again, the color catchers finally came out white. Try it and you shouldn't have any issues with it bleeding. Good luck!!!
