I ordered a photo book on Shutterfly that I am planning on using as a guestbook. I did some lurking and read that people suggested using fine tip Sharpies with them. However, I got the guestbook in the mail today and the pages seem a bit slick...typical photo book paper really. But it makes me nervous that the Sharpies may be too wet. I don't want it to rub off on people's hands or other pages if it doesn't dry before the next person writes or turns the page. Has anyone had that problem or is that not a problem at all? Thanks in advance
