Luckily, I have never had fabric bleed. I usually make queen size quilts, and I buy my fabric at LQS and wash with 3 color catchers to make sure all is okay before I gift them. Just this past week, I was making metallic/neutral placemats and pre-washed my fabric (which I never do but did not want any lumps or shrinkage in my placemats) and had one piece lose its metallic, which made it useless after that. It was the Moda grunge that has the metallic stars on them. I called LQS, and they are going to tell their customers and issue a refund to me.
