Thank you all. I specifically marked the quilt top before I basted it together so that none of the blue marker could have soaked into the batting. Not to say it couldn't permeate the bat and possibly the backing once water is used to remove the mark. It may remain one of life's little mysteries. Hope to bind it in the next couple of days then wash/soak it. I'll let you know how it turns out. Again, thanks for your help.
