DARK KNOWLEDGE, the bookmark.
Awesome, Keith! Did you design them or did the publisher?
I did. Sometimes it's fun being a geek. I did it for STRUCK too, and they came out great, so I did one for DK. I use overnightpress.com Very happy with them. You design it to their dimensions, upload it, and order. It's something like 14 cents/bookmark (American) for the delivered bookmarks if you order 250 and hit one of their specials.
