That is great! Thanks so much.

Love these pens, don't freeze my quilts and I live in Sunny California so don't have to worry about freezing temps. :thumbup:

If a quilt of mine survives for many generations I won't be around to know if the ink came back or not so why the worry. Now days if an old quilt surfaces with pencil markings left on it it is considered a real treasure! From what I could find online the chemicals used for the gel ink are not harmful to natural fibers.

I am using my Frixion black pen to draw around my tiny twister squares today. I gave up on cutting them out with the rotary cutter (before I lose a finger) and I am using my scissors on the Frixion marks. Working great!

I love my pen. I don't put my quilts in the freezer, so I am O K.

I don't think the concern here is about whether you freeze your quilts or not. Not many people I know of do that...

What I think is the concern is the reaction of the chemical ink to both heat and cold. If it can be completely washed out, there should be no concern. But, if that chemical residue remains in the fabric, it could cause problems in the quilt down the road.

Your great-great grandchild may cherish that quilt you made beyond your imagining and it would be a shame for some old chemical residue left in it to be eating away at the fibers and utimately destroying it.

Are you not worried about the fact the chemical is still in the quilt even after it disappears? I would be worried that something in the environment could effect it and turn the area where marked into some other gross color.

Many people don't read the posts (other than the OP) so they are not even seeing our references to the chemicals staying in the fabric. It's one of my pet peeves about message boards. I am easily annoyed, I guess.

But doesn't the ink wash out?

Same here and I love them!!!
