On the reverse side I started with a field of red and added the text. I'm not aware of a consumer-grade printer that is capable of producing 2-sided documents with perfect registration, so this is how I get around making the project less unforgiving in the cutting-out process.
I invested in a small cutting rail and self-healing mat that will fit easily in a laptop case or backpack.
A handy trick is to paint the cap of your X-Acto knife with nail polish; you don't want it disappearing on you, leaving you with a bare, dangerous blade.
Place the sheet of bookmarks, face up, on the self-healing mat. Lie the cutting rail on it with just the tiniest amount of the image showing. Make sure your blade is sharp…
…and start cutting them out. I like to leave the white part intact; it gives the remaining sheet more integrity as you go, and leaves less bits and pieces of paper all over the place.
Here's how it looks on the reverse. Plan ahead for upcoming holidays and special occasions; one parishioner mentioned he'd like to have TWO, one for the hymnal, one for the Book of Common Prayer. That might be a bit more than this bookmark factory can handle!
