Write a scene in which you move from “out-of-scene” to “in-scene” (or vice versa). If you’re not clear on the difference, check out these two places where the narration moves from out-of-scene to in-scene in The Bark of the Bog Owl:
p. 49-50 (out-of-scene to the end of p.49, in-scene at the top of p.50)
p. 56 (out-of-scene before the printer’s mark, in-scene after printer’s mark)
