Well I went to Joanns yesterday and they really had a poor selection of choices. I ended up buying a disappearing pen. Worked great on all the white fab and areas with white. But on the black fab it doesnt show up at all. It is purple and I thought it might but no go lol. If I get a chance this weekend I may go to my lqs and see what they have. I may try the chaco liners. Several people seem to like those. Thank you for the help ladies
