What's the best way to trim them? Scissors? Exacto knife?
I don't know, as I've never done this. My best guess is small craft scissors, as to work with a X-Acto knife, you have to bear down on a surface to slice. Here, there is no icing "surface" under most of the paper, so I doubt the X-Acto will result in controllable cuts. Also, it's more of a slicing tool (it cuts by dragging it), which may "fray" the edges of the paper more than a straight up-and-down scissors-cut would. My best advice is to test on a few cookies before rolling out to the entire set; I apply this same principle to all of my decorating. When in doubt, test first.
