Somewhere here on the board someone used press and seal and the pen they used to mark it somehow got on the quilt. I don't know if it went thru the press and seal or rubbed off. But they were heartbroken because it wouldn't come off.
My biggest problem is that my quilts are usually light and dark. I never know what to use to mark them. I love the Frixion pens but what should I use on the dark fabric. I hate to keep switching pens as I mark.
