Screens invite scrolling. Paper asks you to commit a line. In Millbrook we keep both: a large display for shared viewing, and printed sheets for personal markup.
Beginners who only ever pinch-zoom often skip the boring middle of a trend. On paper, that middle sits in front of them at a fixed scale. Mentors can see whether a student is inventing levels that only exist at one zoom setting.
If you join a workshop, expect graphite on your fingers. If you mentor by video, we still post or email printable sheets so the homework is not limited to whatever your platform can draw in three clicks.
