I have used the Clover White Marker pen for years to help with applique and marking where to place vines and stems. I got to wondering about the chemicals used in it also.
I will show what I did incase anyone is interested.

I will be VERY careful if and when I use these pens again. I will use them I am quite sure especially for projects like the dinosaurs I made. You have to mark each piece and sew corners and all so it really comes in handy. I will just make sure I only mark where I am going to trim off.
There is no telling what the chemicals will do to the fabric over time. It may weaken it or discolor it further. I can see more testing in the future.
