Object Drawing Lessons
Contour line drawing asks you to describe an object's visible edges with one continuous line, without shading or interior detail. This lesson guides you through a bedroom scene containing a bed, a lamp, and a chair. You will practice keeping the line unbroken, handling overlaps where objects cross, and resisting the urge to draw internal features like mattress seams or lamp switches. The goal is a clear, readable outline that captures the arrangement and proportions of the furniture. All measurements and numerical examples here are hypothetical; measure your own paper and tools before starting.

Understanding Single-Line Contour
A contour line traces the boundary where a form meets space or another form. In a single-line study, you keep the drawing tool on the paper from start to finish, letting the line loop back or travel along shared edges when needed. This constraint forces you to plan the order of edges and to observe how shapes connect.
For a bedroom scene, begin with the largest shape: the bed. Its outer boundary includes the headboard, mattress edge, and footboard. The lamp and chair are smaller shapes that overlap or sit beside the bed. You will decide a drawing order that lets you move from one object to the next without lifting the pen.
- Place your paper and choose a starting point on the bed's outer edge.
- Trace the bed's visible boundary, including the headboard profile and the mattress side.
- Move to the lamp, following its base, stem, and shade outline.
- Continue to the chair, outlining its back, seat, and legs.
- Return to the bed if needed to close any open edge, keeping the line unbroken.
Handling Overlaps and Shared Edges
When one object sits in front of another, the front object's contour interrupts the rear object's contour. In a single-line drawing, you can handle this by tracing the front edge, then following the rear edge up to the point where it disappears behind the front object. Do not draw a line through the front object to continue the rear one.
Shared edges occur where two objects touch, such as a chair pushed against the bed. You may trace the shared edge once and then continue along the next visible boundary. The line remains continuous because you are following the actual visible contour, not inventing a separation.
- Identify which object is in front at each crossing.
- Trace the front object's contour first at that crossing.
- Follow the rear object's contour only up to the occlusion point.
- Resume the rear contour on the other side of the front object if it reappears.
- Keep the pen on the paper by retracing a short segment or looping at a junction.
Avoiding Interior Detail Lines
Interior detail lines include mattress seams, lamp switches, chair cushion creases, and headboard panel divisions. In a contour study, these are omitted unless they define a major change in the outer silhouette. For example, a thick headboard with a visible top edge is part of the contour; a decorative groove on its face is interior detail.
Omitting interior lines keeps the drawing readable as a single outline and helps you focus on proportion and overlap. If you are unsure whether a line is contour or detail, ask whether it separates the object from empty space or from another object. If it only separates two parts of the same object's surface, leave it out.
- Scan each object for lines that do not change its outer boundary.
- Mark those as interior detail and exclude them from the single line.
- Keep only edges where the object meets background or another object.
- Check that the final line describes the silhouette of each piece of furniture.
Proportion and Placement Checks
Before drawing, compare the bed's length to its height and to the chair's seat height. Use your pencil or a small paper strip to compare these distances on the reference arrangement. Label any numerical values you choose as hypothetical examples; for instance, you might decide the bed is about twice as long as it is high in your sketch.
Place the lamp so its shade overlaps the headboard or wall edge, and the chair so its back overlaps the bed's side. These overlaps create clear contour junctions and make the single-line path more interesting. Check that the chair's legs reach the floor line and that the lamp base sits on a surface.
- Compare bed length to bed height using a pencil or paper strip.
- Compare chair seat height to bed mattress height.
- Decide where the lamp shade overlaps the headboard or wall.
- Decide where the chair back overlaps the bed side.
- Verify that all furniture contacts the floor or a surface.
Worked example
Describe a single-line contour path for a bedroom with a bed on the left, a lamp on a nightstand to the right of the headboard, and a chair at the foot of the bed. The lamp shade overlaps the headboard edge, and the chair back overlaps the bed's footboard.
Worked answer
Start at the top-left corner of the headboard. Trace the headboard's left edge down to the mattress, then along the mattress side to the footboard. At the footboard, the chair back overlaps: trace the chair back's top edge first, then follow the footboard edge up to the chair back, stop, and resume the footboard on the other side of the chair. Continue around the chair's seat and legs, then return to the bed's footboard and trace its remaining edge. Move to the nightstand and lamp: trace the lamp base, stem, and shade. Where the shade overlaps the headboard, trace the shade first, then follow the headboard edge to the shade, stop, and resume the headboard above the shade. Close the path by returning to the starting point along the headboard's top edge. Omit mattress seams, lamp switch, and chair cushion creases.
Four practice exercises
Exercise 1
A bed is drawn with its headboard on the left and footboard on the right. A chair sits in front of the footboard, overlapping it. Describe the order of contour tracing at the overlap and how to keep the line continuous.
Show answer and check
Trace the chair's back contour first where it is in front. Follow the footboard edge up to the chair back, stop, and resume the footboard on the other side of the chair. Keep the line continuous by retracing a short segment at the junction or by looping at the stop point.
Why: The front object's contour interrupts the rear object's contour. Stopping and resuming avoids drawing through the front object, and a short retrace keeps the pen on the paper.
Check: Verify that no line passes through the chair back to continue the footboard, and that the footboard contour resumes on the far side of the chair.
Exercise 2
A lamp shade overlaps the top edge of a headboard. The lamp is in front. List the contour segments in order from the lamp base to the headboard top, including the overlap handling.
Show answer and check
Trace the lamp base, stem, and shade outline. At the shade's lower edge where it meets the headboard, trace the shade first. Then follow the headboard top edge to the shade, stop, and resume the headboard top edge above the shade. Continue to the headboard's outer corner.
Why: The shade is in front, so its contour is uninterrupted. The headboard contour is interrupted at the shade and resumes above it.
Check: Check that the headboard top edge does not continue behind the shade and that the shade outline is complete.
Exercise 3
You are drawing a bed with a visible mattress seam and a headboard with a decorative groove. Decide which lines to include in the single-line contour and which to omit. Explain your choice.
Show answer and check
Include the bed's outer boundary: headboard profile, mattress side, and footboard. Omit the mattress seam and the headboard groove because they are interior detail lines that do not change the outer silhouette.
Why: Contour lines separate the object from space or other objects. Interior details separate parts of the same surface and are excluded in a contour study.
Check: Confirm that every included line lies on the outer boundary of the bed or another object, and that no included line is purely decorative.
Exercise 4
A chair is placed beside a bed so that the chair's back touches the bed's side. Describe how to trace the shared edge once and continue to the chair's seat and legs without lifting the pen.
Show answer and check
Trace the shared edge where the chair back meets the bed side. At the end of the shared edge, continue along the chair back's outer contour, then down to the seat and legs. Keep the line continuous by following the visible boundary; the shared edge is drawn once.
Why: A shared edge is a single visible contour for both objects. Tracing it once avoids duplication and keeps the line continuous.
Check: Verify that the shared edge is not drawn twice and that the line flows from the shared edge into the chair's outer contour without a break.
Common mistakes
- Lifting the pen to start a new object. Plan a path that connects objects through shared edges or by retracing a short segment at a junction.
- Drawing interior details such as mattress seams or lamp switches. Exclude any line that does not separate the object from background or another object.
- Continuing a rear object's contour through a front object. Stop the rear contour at the occlusion point and resume it on the other side if visible.
- Making the bed too short or the chair too tall relative to each other. Compare key distances with a pencil or paper strip before committing to the line.
Self-check rubric
- The line is continuous from start to finish, with no lifts; short retraces at junctions are allowed.
- Only outer contours are drawn; interior detail lines such as seams and switches are omitted.
- Overlaps are handled by stopping the rear contour at the front object and resuming it on the other side.
- The bed, lamp, and chair are all present and readable as distinct forms.
- Proportions are plausible: the bed is longer than it is high, and the chair seat is lower than the mattress.
- The drawing uses a defined convention for single-line contour, such as retracing at junctions, and this convention is applied consistently.
Questions and answers
Can I retrace a line to keep the pen on the paper?
Yes. Retracing a short segment at a junction is an accepted convention for single-line contour. The line remains continuous even if it doubles back briefly.
Should I draw the wall or floor line?
Include a floor line only where furniture meets it and the line helps describe placement. Avoid drawing full room boundaries unless they are part of the furniture silhouette.
What if the lamp shade overlaps the headboard?
Trace the lamp shade's contour first where it is in front, then follow the headboard edge up to the shade and resume it on the other side.
How do I know if a line is interior detail?
If the line only separates two parts of the same object's surface and does not change the outer silhouette, it is interior detail and should be omitted.
