Well recently, I discovered that when I tested the pen on some batik fabric, the pen marks disappeared, but so did some of the ink in the fabric. I switched to a chalk pen, but I thought that my discovery was interesting and it could be used to my advantage.
I was reading Paulette's blog the other day, and she had somebody reporting this as a problem too. Well I thought I'd repeat the test today using four pieces of batiks. Using the FriXion pen, I printed my name on the test fabrics. I waited 5 minutes or so, then ironed it off.
The color lifts out. Every time. Every batik I've tested, has the same result.
So if you are marking temporary lines on your batiks, don't use the FriXion pens.
But knowing this, I know that some of you are pretty creative and might find a way to use this FriXion pen "feature" in your batik projects.
Maybe write, "Congratulations on your new apartment", or "Happy Anniversary" Or simply sign and date the front of your project instead of making a label for the back.
Can you think of other ways that this "feature" would be useful?
