Lines: Diagonal
Work with the Diagonal Line as a simple spatial reference for double-prop patterning. Nikki Scarano frames the diagonals as 45-degree pathways that form an X, giving you two clear lines to aim for when placing your hands and prop paths.
Use this linework to tidy up hand passes and to track the wicks of fans (or other double props) across consistent diagonals. Drilling against these imagined lines supports cleaner movement, clearer symmetry, and more reliable orientation when transitioning between mirrored and crossing pathways.
