I'm working on a page that I want to use chipboard embellishments on. They are speech bubbles, so I want to write on them. I tested a Sharpie on one piece, and it doesn't really show up that well. These are finished (paper coated?) pieces as opposed to the "raw" chipboard. So, I would like to know if there are any pens out there that are better for writing on these pieces.
TIA!
