You should buy Shout color catchers. I had a similar experience. My husband's favorite wallhanging with his Eagle was very dusty. I always prewash all my fabric before I sew. Put it in the bathtub in cold water and couldn't believe that the red ran into the white and was pink. Didn't dry it but a few months later put it in the washer in cold water with a sheet and it all came out!! Good luck with yours.
