Ghost Line Drawing: Single-Weight Outline and Draped Sheet Contours

How to use this drawing lesson

This lesson teaches a ghost line drawing built from draped sheet contours and rendered with a single-weight outline. The goal is a clean, readable silhouette where every line carries the same visual weight and the folds describe cloth falling over an implied form. You will plan the sheet as a set of hanging curves, then commit to one line thickness throughout. The convention is explicit: single-weight means the outline and interior contour lines are drawn at the same thickness, with no shading, hatching, or tapering. Hand-drawn contour shapes vary, so the rubric rewards consistent weight and logical drape rather than one exact silhouette. All measurements below are hypothetical examples; measure your own paper and pen before drawing.

Plan the draped sheet before drawing

A ghost reads as cloth, not as a blob. Begin by imagining a sheet dropped over a rounded form: the fabric pulls tight over the top, gathers at the sides, and hangs in soft vertical folds toward the hem. Sketch these as light guide curves first, then refine them into final contours.

Use a single-weight convention from the start. Choose one pen or pencil and keep the same pressure for every final line. If you use a pencil, do not switch to a darker grade midway. The guide lines can be lighter, but the committed outline and fold lines must match in thickness.

1. Draw a rounded top curve to suggest the head form under the sheet.
2. Add side curves that fall outward and downward to the chosen widest level, then connect smoothly to the hem; they may narrow slightly after the widest level.
3. Place three to five interior fold lines that follow the direction of gravity, curving gently rather than zigzagging.
4. Close the hem with a soft wavy line that connects the side curves.
5. Trace over the final contours with one consistent line weight, then erase or ignore the guides.

Build the silhouette and hem

The silhouette is the outer boundary of the sheet. Keep it continuous and calm. Begin with a rounded top over the implied form, then let the sides broaden toward the chosen widest level. In the general construction use roughly two-thirds of the height, but an explicit exercise fraction overrides that guide. Below that level the sides may narrow slightly into the hem. The widest cross-section and the hem are separate measurements; do not assume that they have the same width.

Keep the hem simple. Three or four shallow dips are enough to suggest cloth. Deep, repeated scallops can make the drawing look like a curtain rather than a draped sheet.

1. Mark the widest level at roughly two-thirds of the total height unless the exercise gives a different fraction; exercise 1 explicitly uses one-third.
2. Draw the left and right outer edges as smooth curves from the top to the hem.
3. Add shallow hem waves, keeping each wave wider than it is deep.
4. Check that the hem does not cross the side edges; it should meet them cleanly.

Place interior fold contours

Interior folds explain how the cloth hangs. They should start near the top or sides and flow downward, spreading slightly as they approach the hem. Avoid folds that stop abruptly in the middle of the sheet; each fold should either reach the hem or fade into another fold.

Use the same line weight as the outline. The folds are contours, not shading. Their job is to describe direction and volume through placement alone.

1. Draw one central fold that runs from the top curve toward the hem.
2. Add two side folds that mirror each other loosely, not exactly.
3. Keep spacing uneven to avoid a mechanical look.
4. Confirm every fold line is the same thickness as the outline.

Check weight and readability

Single-weight line art depends on consistency. After drawing, compare the outline and the interior folds side by side. If one line looks heavier, redraw it with the same tool and pressure rather than thickening the others to match.

Readability matters more than detail. A viewer should recognize a draped sheet from the silhouette alone. If the folds compete with the outline, reduce their number rather than adding more.

1. Hold the drawing at arm's length and check that the silhouette reads clearly.
2. Compare line thickness at the top, sides, and hem.
3. Remove or simplify any fold that does not support the drape.
4. Confirm there is no shading, hatching, or tapering anywhere in the final line work.

Worked example

A ghost sheet is planned with a total height of 12 cm on paper. The widest point is at two-thirds of the height. Calculate the height of the widest point from the top, and state how many shallow hem waves you would use if each wave is about 2 cm wide across a 10 cm hem.

The widest point is at 8 cm from the top. A 10 cm hem with 2 cm waves gives 5 waves, but 3 to 4 shallow waves are recommended for a calm draped look, so use 4 waves of about 2.5 cm each.

Four exercises with answers

Check your drawing

• Silhouette reads as a draped sheet from arm's length.
• Outline and interior folds share one consistent line weight.
• Interior folds follow gravity and reach the hem or fade logically.
• Hem uses shallow waves, each wider than deep.
• No shading, hatching, or tapering is present.
• Valid alternative shapes are accepted if weight and drape logic hold.

Common mistakes

Varying line weight between the outline and interior folds.

Use one tool and one pressure for all final lines; redraw inconsistent lines instead of thickening others.

Drawing folds as zigzags or sharp angles.

Curve each fold gently in the direction of gravity and let it reach the hem or fade into another fold.

Making the hem too deeply scalloped.

Use three or four shallow waves, each wider than it is deep, to suggest cloth rather than a curtain.

Adding shading or hatching to suggest volume.

Describe volume through fold placement only; keep the drawing strictly single-weight line art.

Frequently asked questions

What does single-weight mean in this lesson?

It means the outline and all interior contour lines are drawn at the same thickness, with no tapering, shading, or hatching.

How many folds should the sheet have?

Three to five interior folds are usually enough. Fewer folds read more clearly; more folds can clutter the silhouette.

Can I use a pencil instead of a pen?

Yes, as long as you keep one consistent grade and pressure for the final lines. Do not switch to a darker pencil midway.

Do I need to draw the body under the sheet?

No. The rounded top curve and the widening sides imply the form. The sheet itself carries the drawing.
