I have tested that new pen. I was told that freezing will make the marks re-appear, and it does!!! I marked several pieces of cotton fabric. The lines show up great.
I ironed the fabrics, the marks became invisible. I washed the fabrics to get the marks out, then put the fabrics in the freezer for a couple of hours and the marks were all back....very visible!
That means to me that the chemicals are still in the fabrics, and you don't want to use quilts in a cold environment! WHAT???
I won't use these pens on my quilts. There is no telling what the chemicals will do to the fabric several years from now.

However it would be a fun project for children to send secret notes to each other!!

It initially looks wonderful, but as Margarita suggests, it is always best to try out any new marking pen on a scrap first. I would also be interested to know how these marking affect the fabric in the long run, but I guess we will have to wait half a dozen years or so before we find out.

The pens are great, but not for BATIKS, or other dyed (?) fabrics. Be sure to test before using on your quilts.
I have been using one to mark my seam lines on my Dear Jane quilt, so far so good.
One of my friends used it on a batik, and when she used her iron to erase the line, it turned white, (as if it bleached it)
it took out the color of the fabric.
