I make a cardboard template on the plane, then mark the Monokote with a sharpie.Then I cut it on a plastic cutting board. The plastic makes the blades last longer, although they never last very long anyway. I've found that trying to follow a template on the Monokote usually results in mistakes as I tend to press into the template or will drift away in an attempt not to press into it. But the black sharpie line is easy to follow for good results every time.
