Object Drawing Lessons
Continuous ink contour drawing asks you to describe an object's visible edges with one unbroken ink line. You do not lift the pen, retrace, or shade. The goal is deliberate, connected looking: every edge you draw must link to the next without a gap. Proportion accuracy and blind-contour variation are outside this task. Work on scrap paper first, then use the blank frames described in the resource plan. Keep your pen moving slowly and let the line wander around the form. If you make a mistake, continue from where you are; do not restart. The convention below defines what counts as continuous and how to judge your own work fairly.

The continuous-line convention
A continuous ink contour line is one visible mark that never lifts from the paper. You may change direction, curve, loop, and cross earlier parts of the line, but you may not create a separate stroke or retrace an existing segment. Gaps, dots, and retraced segments break continuity. Ink means a pen that leaves a consistent mark; pencil is acceptable only for early practice, but the assessed work uses ink.
X-height is the distance from baseline to midline in your handwriting; letter styles vary, so do not copy a single model. For drawing, use the same idea: decide a baseline and midline for the object's overall height, then keep your line within that band unless the object genuinely extends beyond it. This is a planning aid, not a universal standard.
- Place the object where you can see it without moving your head much.
- Choose a starting point on an outer edge and touch the pen down once.
- Move slowly along the edge; when you reach a junction, continue into the next visible edge without lifting.
- If you lose track, pause with the pen still touching paper, look again, then continue.
- Finish by returning near the start or by ending at a natural terminal edge; do not add a separate closing stroke.
Planning the line before ink
Before inking, trace the object's main edges in the air with your finger. Identify one continuous route that covers the silhouette and at least two internal edges. A mug, for example, can be drawn from the rim, down the side, around the base, up the handle, and back to the rim. Decide where the line will cross itself; crossings are allowed and often necessary.
Set a hypothetical frame size, such as 12 cm by 12 cm, and mark a baseline and midline lightly in pencil. These numerical values are examples only; measure your actual paper and pen. Keep the ink line inside the frame. If the object is taller than the frame, choose a smaller object or a larger frame before starting.
- Air-trace one continuous route that includes the silhouette and two internal edges.
- Mark a light pencil baseline and midline on the paper.
- Test the route with a dry pen, keeping the tip on the paper.
- Load the pen and begin at the chosen start point.
- Do not lift until the route is complete.
Judging continuity and line quality
Use a simple checklist: no gaps, no separate strokes, no retraced segments, and no shading. Crossings are fine. A line that wobbles is still valid if it is continuous. A line that is smooth but has a gap is not. Judge the drawing by continuity first, then by whether the line describes the object's visible edges.
Valid alternatives exist. You may start at a different edge, cross the form in a different order, or include more internal edges. Two learners can produce different continuous lines from the same object and both pass. The rubric rewards a single unbroken mark and clear edge description, not a single correct route.
- Check for gaps by holding the paper at eye level and looking along the line.
- Check for separate strokes by counting pen-down events; there should be one.
- Check for retracing by looking for doubled ink over the same segment.
- Check that at least two internal edges are described.
- Record one improvement for the next attempt.
Worked example
Draw a simple mug in one continuous ink line inside a 12 cm by 12 cm frame. Include the rim, one side, the base, the handle, and the other side. Do not shade.
Worked answer
Start at the left rim. Curve across the rim to the right, down the right side to the base, across the base to the left, up the left side, then loop out to form the handle and return to the left rim. The line crosses itself once near the handle. No gaps, no separate strokes, no shading. The mug is described by one unbroken mark.
Four practice exercises
Exercise 1
Draw a spoon in one continuous ink line. Include the bowl outline, the handle, and one internal edge of the bowl. Use a 10 cm by 10 cm frame.
Show answer and check
A valid answer starts at the bowl tip, curves around the bowl, runs up the handle, returns along the other side of the handle, and closes near the bowl. One internal edge, such as the bowl's inner curve, is included. The line crosses itself once.
Why: The route covers the silhouette and one internal edge without lifting the pen. Crossings are allowed.
Check: Count pen-down events: one. Look for gaps along the line. Confirm at least one internal edge is present.
Exercise 2
Draw a key in one continuous ink line. Include the bow, the shaft, and two teeth. Keep the line inside a 12 cm by 8 cm frame.
Show answer and check
A valid answer starts at the bow, loops around it, runs along the shaft, turns into the first tooth, returns to the shaft, turns into the second tooth, and ends at the shaft tip. The line may cross at the bow.
Why: The route links bow, shaft, and two teeth in one mark. The frame is respected.
Check: Check that the line never lifts, that two teeth are described, and that the drawing stays inside the frame.
Exercise 3
Draw a pair of scissors in one continuous ink line. Include both handles, the pivot area, and one blade edge. Use a 15 cm by 10 cm frame.
Show answer and check
A valid answer starts at one handle, loops through it, crosses the pivot area, runs along one blade edge, returns through the pivot, loops through the second handle, and ends near the first handle. The line crosses itself at least twice.
Why: Scissors require crossings to link handles and blades. The route remains one mark.
Check: Count pen-down events: one. Confirm both handles and one blade edge are described. Check for retracing.
Exercise 4
Draw a small plant pot with one leaf in one continuous ink line. Include the pot rim, the pot base, the stem, and the leaf outline. Use a 12 cm by 12 cm frame.
Show answer and check
A valid answer starts at the rim, goes down the pot side, across the base, up the other side, back to the rim, then up the stem, around the leaf, and back down the stem to the rim. The line crosses once where the stem meets the rim.
Why: The route links pot and leaf without lifting. The crossing at the rim is allowed.
Check: Check for gaps, separate strokes, and retracing. Confirm the leaf outline and pot base are present.
Common mistakes
- Lifting the pen to start a new edge. Pause with the pen touching paper, look, then continue from the same point.
- Retracing a line to correct it. Leave the imperfect line and continue; retracing breaks the convention.
- Adding shading with separate strokes. Omit shading entirely; this task is contour only.
- Restarting the whole drawing after a wobble. Continue from the wobble; continuity matters more than smoothness.
Self-check rubric
- One pen-down event: the line is unbroken from start to finish.
- No retraced segments and no separate shading strokes.
- Silhouette is described by the continuous line.
- At least two internal edges are included.
- Line stays within the chosen frame.
- Valid alternative routes are accepted if continuity and edge description are present.
Questions and answers
Can the line cross itself?
Yes. Crossings are allowed and often needed to describe handles, rims, and internal edges.
May I use pencil?
Pencil is fine for early practice, but the assessed drawing uses ink so continuity is visible.
What if the object is too tall for the frame?
Choose a smaller object or a larger frame before starting; do not crop the line mid-drawing.
Is a wobbly line acceptable?
Yes, if it is continuous and describes visible edges. Smoothness is not the criterion.
