Marks that speak
- Line quality 线条质感 is how a line looks and feels: thick or thin, dark or light, fast or slow.
- The AP rubric lists mark-making 笔触 first among its drawing skills.
- The same edge drawn with different lines tells a different story.

Weight, tone, and speed are line qualities; sound is not.
Weighted and lost-and-found
- A weighted line 轻重线条 changes thickness: press harder where the form turns away or carries weight.
- Lost-and-found lines 虚实线条 fade out and return — the eye completes the missing edge.
- Varying one line beats drawing the same edge three times.

Weighted = form; lost-and-found = suggestion; even = neutral.
Confidence and direction
- Confident lines come from the shoulder and elbow, not only the fingers.
- Direction carries feeling: horizontal is calm, vertical is firm, diagonal is active.
- Examiners read line quality at a glance — warm up before serious drawing.
Confident lines are drawn mostly from the fingers.

Confident lines come from the shoulder and elbow; fingers alone make small, timid marks.
Horizontal lines feel calm, vertical lines feel firm, and ____ lines feel active.

Diagonal direction reads as movement and action.
A timid, scratchy repeated edge does not become confident by adding more strokes. Slow down, decide where the line goes, then draw it once, from the arm.
Drawing an apple: the line is thin and light on the lit top, grows thick and dark under the shaded base, disappears where the apple melts into shadow, and reappears at the stem. One line, four decisions.
Line quality is the first drawing skill: vary weight with pressure, let edges be lost and found, draw from the arm, and use direction (calm horizontal, firm vertical, active diagonal) on purpose.
Write from one line with 5 turns
- The pencil stays down and changes direction 5 times.
A student keeps the pencil on the paper and changes direction 5 times before lifting it. How many lines is that mark?
One continuous touch of the pencil is one line.
How many lines did the student draw?

The pencil stayed down, so the five turns belong to one line.
