I use erasable pen for sewing doll clothes. It was ok until lately. First when i serge the project with the marking was still there. When i washed it, goodness! It was hard to disappear. Second, today. I used brocade fabric for the clothes. I thought, it would be ok, no problem. All i need was to soak it over night. But today, i found the mark was still there! It is even more difficult to remove. I’m trying special remover now. I used the same pen on cotton. It was ok! .
I think, from now on, i must test the pen even it’s ok on other fabric. I think, for some fabric, i prefer Erasable Spidol though. I think, the ‘water’ is still a lot more than the color liquid. It’s easier to be removed. Oh, there are other kind of erasable/washable marker, a pencil. I think, it’s also easier to be removed. Yet, again, must try it first before trying on a ‘particular’ fabric.
So far, the erasable pen is relatively easy to be removed if i used it on satin-like fabric, cotton, sheer. I haven’t tried it on canvas or medium fabric. I usually prefer spidol over pen when working with thicker fabric.
