You can always tell when I’ve been working on a big batch of pages because I start making those little scribbly notes to myself in the top left of every panel. It usually doesn’t survive my scribbling over it, but when I first start these big batches I also usually just mark down the basic placement of each individual character as a circle where the head will eventually be and then I also scribble their name or initials on each circle.
Although on this page we mostly had just a lot of random one-off extra characters, and then Therese and Staefe ( or St + Th according to the note).
