See, this is the part that most people think I'm talking about when I say I won't use the pens because those marks don't entirely disappear. I'm not worried about the marks coming back if I send my quilt to the North Pole and it gets cold. I'm worried about the fact that
because they come back, there is obviously some ink still on/in the fabric, and nowhere does it say they are acid-free and archival quality! I'd much rather use my Sewline fabric pencil, which is designed specifically for fabric use.
