Thank you Holice ... for all the info!
You've made me really think about the pink and yellow chalk rollers that I've been using. Maybe pretty isn't such a good idea!!
I'll check out the art supplies next time I'm near a store that might have them and see if I can have some luck!
The ceramic mechanical pencils ... would these be art supplies? drafting? or?
Petey ... I have the Frixxion pens too, and really like them.
Most of the time, I use mine for marking the wrong side of fabric.
However, you may find that they bleach out fabrics.
I know I have had that happen on both dark and light.
So as
Holice suggests ... test test and test again!
