Build the movement before building the alphabet.
The practice room is arranged by physical variable rather than letter order. Each session has a warm-up, one diagnostic question, a controlled drill and a short transfer line.
Hairline to swell
Start with low-pressure entry strokes, add pressure progressively, then release before the baseline. Compare where the widest point occurs.
Parallel slant
Write repeated stems against a guide. Circle only the strokes that drift, then rotate the page before changing your wrist position.
Counter shapes
Build repeated arches and ovals while watching the white shapes between strokes. Adjust spacing without changing letter height.
Exit-to-entry joins
Practise two-letter joins where the exit must arrive at a consistent entry point without pulling the second form out of proportion.

Know which part of the tool changes the mark.
Before blaming hand control, check nib alignment, tine spread, holder angle and paper interaction. The lessons distinguish tool problems from movement problems.
