Freehand sketching techniques

The following is a guide to freehand sketching techniques.

Horizontal lines

When you are drawing horizontal lines, your hand slides from left to right. Measure the distance between the two established points with your eyes. Short joining lines may provide an acceptable finish especially when drawing longer lines.

Vertical lines
Use a wrist movement from top to bottom when you draw a vertical line.
Sloping lines
When you are drawing a line from upper left to lower right, make the movement with your wrist, holding your hands above the line. Draw lines from lower left to upper right by sliding your whole hand. When drawing lines from upper right to lower left, use your wrist. Your hand should always be below the line.
Hand position
Position your hand at the end of the pencil to gain more control and precision and darker markings. Positioning your hand further up the pencil gives you less control, producing lighter markings.

To keep lines straight, move your entire arm. No shape is more important in drawing architecture than a simple straight line.

If you want to draw straight lines without a ruler, you must lock your wrist and elbow.
