So you opened up the 2D animation environment, and made a character, perhaps even animated it. Admiring your handiwork, you decide to add a background. Your background drawing is on top of your character now, and you google desperately searching for how to change the layer order for your background object. Wringing your hands in despair and cursing violently you delete your file and vow never to open Blender again…but wait! Do not despair! With your background object selected, go into side view and nudge it back a little bit. Grease pencil objects exist in physical space. Or you can go to your numerical input panel and do it with the sliders.
