Hi all. I got this great dark-ish wooden board on Etsy for our guests to sign instead of a book. I had figured we would use white paint pens to write on it until it dawned on me that they would smear really badly when people are signing. Will silver or gold metallic sharpie markers show up on the dark wood? I know permanent markers wont smear... Has anyone done anything like this? If so, can you upload a pic?
