If the markings of these pens come back in the cold, does that mean
if they are washed in cold water, the same thing will happen?
Just curious.

There have been too many posts about this product so I haven't used it. It will be interesting to see what others have come up with.

I agree with Maniac. These pens were designed for paper, not fabric.
The 'reappearing' lines show when the fabric is cold, so cold water wash may make them visible, but when returned to room temp, they should go away. I have read, however, of some fabrics that have ghost lines that show all the time.

I understand they do come back in cold until they have been washed what I would do is try it for yourself on a sample piece see what happens.

Thanks! That sounds like a good idea.
