I had already quilted it and made sure that the edges where sewn down and then stuck in the washer. I took 3 washings with Grandma's Stain stick being the final effort that got it out. I do not know what was happening with it--but she did tell me later than she had starched the fabric first. Won't use again .
Good to know. I'm a starcher. I usually stick with Sewline pencil (white and black only).
If I had to use a colored marker of any kind I would test first.
