In the section about applications for pigma micron pens:

When referring to textile / quilting usage

"* Please note - the inks on fabrics are for " decorative purposes only" - meaning do not launder. Use on pre- laundered textile, 100% cotton. And most importantly, to pre-test on material scraps prior to final application."

Oh duh, glad somebody thought to look it up! Thanks bearisgray :) that explains why it kept fading when I did my own little experiments with my Pigmas.

After using the pen - Press with a hot iron - that sets it. Works for me. Not sure why it does not say on the pack.

even though it never said to heat set, I always did. even heat set signature blocks I collected from swaps around the world. worked well.

My friend got interfacing glue on a piece that I wrote a saying on and I decided to try using Goof Off. It took the glue off, I washed the Goof Off out and my writing was not messed up at all. I then tried a piece I wrote gunk on and even cloroxed it and the writing did not come out or faded. I really like the pigma pens.

I will try the heat-set - thanks!
