I've not had this problem. I'm also a novice quilter. Somehow, the theory of the thread transferring the die from the backing doesn't make a lot of sense. I'm not questioning that the cotton thread would pick up the loose die from the fabric. The cotton thread would have to have a huge amount of wicking capacity to accomplish that.
If the backing contained that much loose die, wouldn't it stain all of the front, not just the thread and it's surrounding area?
Also, if this is true, wouldn't it make a good argument for using polyester?
