I know that a lot of folks like the Frixion pens for marking. I've heard the stories of the ink coming back in the cold, even after washing. What would concern me, is that if the company says not to use on fabric, in 20, 30, 50 years, will the ink have dissolved or damaged the fabrics? Think of the dyes used in early fabric that have just shredded away. Will this be the quilts marked with Frixion pens in the future? Convenient? yes. Safe to use? The jury is still out on this question. JMHO....
