I use the FriXion pens to mark on fabric -- making HST/QSTs, flying geese, quilting designs, etc. The markings "disappear" when you apply heat. There is always the disclaimer to test the marker on a scrap of your fabric to make sure the marking disappears. When you apply heat, you may still see a slight discoloration on the fabric, which is the chemicals in the ink, but the chemicals are removed when you wash your quilt.
