All that being said ... I have also not had ghost lines appear. My guess is that I use Best Press in my prep work, and perhaps it protects the fabric from the ghosting? I have no idea.

Considering everything, while I do use Frixion pens, I use them cautiously and re-consider the risk and concerns, and whether I can accept any fall out from their use.
