[quote=MISHNJIMThank you. Those are the one's you use for scrapbooking also..right?[/quote]
As long as they have either "waterproof" or "for fabric" on them and are pigment ink they should be O.K. But I always try them on a scrap of fabric, iron it to heat set (I'm not sure if this is necessary but I do it anyway) and wash it and iron it dry. I do this with every pen I use, just in case.
