Object Drawing Lessons
This lesson teaches four small trippy line-pattern motifs that fit inside a compact square: a spiral, a warped wave, a dot ring, and nested contours. The goal is controlled repetition, not a large scene. Work on plain paper with a pencil and a fine-tipped pen. Use a simple convention: x-height means the distance from baseline to midline of your lowercase letters, and letter styles vary, so treat any lettering as optional and separate from the motif. All measurements below are hypothetical examples you can adjust after measuring your own paper and pen. Keep units consistent, use millimeters for spacing, and check arithmetic with simple counts.

Set up a compact motif grid
Draw a 60 mm by 60 mm square lightly in pencil. Mark the center with a small cross. This square is your motif boundary; keep all lines inside it. A 60 mm square is a hypothetical example, so measure your own paper and choose a size that leaves a 10 mm margin around each motif.
Use a fine-tipped pen for final lines and a pencil for guides. Keep your hand supported and rotate the paper rather than twisting your wrist. The four motifs below share the same boundary so you can compare them fairly.
- Measure and draw a 60 mm square in pencil.
- Mark the center cross at 30 mm from each side.
- Label the square with the motif name in small letters, keeping lettering outside the motif area.
- Check that the square is closed and that the center cross is within 1 mm of the true center by measuring both diagonals.
Spiral motif
A spiral is a single line that turns around a center while its distance from the center grows steadily. For a compact motif, aim for four to six quarter turns (one quarter turn is a 90-degree sweep around the center). If you want a numerical guide, a hypothetical example is a starting radius of 2 mm and an increase of 2 mm per quarter turn; adjust after measuring your pen width.
Keep the gap between turns even. Even gaps make the pattern read as trippy rather than messy. If the line crosses itself, the gap was too small or the turn was too tight.
- Place the pen at the center cross and draw a small arc of about 2 mm radius.
- Continue the line around the center, increasing the distance slightly each quarter turn.
- After four to six quarter turns, stop and check that no line touches the square boundary.
- Count the quarter turns and measure the widest gap; if the widest gap is more than twice the narrowest, redraw with a steadier increase.
Warped wave motif
A warped wave is a row of repeating curves whose height changes gradually across the square. Draw three horizontal guide lines at 15 mm, 30 mm, and 45 mm from the bottom edge as a hypothetical example. The middle guide is the baseline for the wave.
Make each wave peak slightly higher or lower than the last, but keep the change small so the pattern stays compact. A repeating wave with a slow warp looks intentional; a random wave looks accidental.
- Draw three light horizontal guides inside the square.
- Start at the left edge on the middle guide and draw a smooth curve up to a peak, then down to the next trough.
- Repeat the curve across the square; if you warp the wave, change the peak height by a small fixed amount such as 1 mm per peak.
- Check that the wave stays inside the square and that the peaks are evenly spaced and countable.
Dot ring and nested contour motifs
A dot ring is a circle of evenly spaced dots with short lines connecting alternate dots. Use a hypothetical example of 12 dots on a 20 mm radius circle; measure your own compass or use a paper guide. Nested contours are closed loops inside each other, each slightly smaller, like a topographic map.
For the dot ring, count the dots before drawing lines so the pattern is regular. For nested contours, start with the outer loop and work inward, keeping the gap between loops even. Both motifs reward slow, countable steps.
- For the dot ring, mark 12 dots evenly around a 20 mm radius circle.
- Connect every second dot; with 12 dots this forms two separate 6-point star polygons (12 lines total).
- For nested contours, draw an outer loop inside the square, then draw a smaller loop inside it with an even gap.
- Repeat inward until you have four loops, then check that no loop touches another.
Worked example
Draw a compact spiral inside a 40 mm square with a center cross. Use a hypothetical starting radius of 2 mm and increase the radius by 2 mm every quarter turn, for four quarter turns. Check that the spiral stays inside the square.
Worked answer
Four quarter turns add 2 mm each, so the final radius is 2 + 2 times 4 = 10 mm. The square's half-width is 20 mm, so the spiral's widest point is 10 mm from the center and leaves 10 mm to the nearest edge. The spiral fits inside the boundary, and the gap between turns is even because each quarter turn adds the same 2 mm.
Four practice exercises
Exercise 1
Draw a spiral in a 50 mm square. Use a hypothetical starting radius of 3 mm and increase by 2 mm every quarter turn, for five quarter turns. State the final radius and whether the spiral fits.
Show answer and check
Five quarter turns add 2 mm each, so the final radius is 3 + 2 times 5 = 13 mm. The square's half-width is 25 mm, so the spiral's widest point is 13 mm from the center and fits inside the 50 mm square.
Why: Each quarter turn adds 2 mm to the radius, and there are five quarter turns, so the radius grows by 10 mm from 3 mm to 13 mm. The square half-width is 25 mm, and 13 mm is less than 25 mm, so the spiral stays inside.
Check: Measure the widest point of the spiral from the center and confirm it is about 13 mm, which is less than 25 mm. Count the quarter turns to confirm five.
Exercise 2
Draw a warped wave across a 60 mm square using three horizontal guides at 15 mm, 30 mm, and 45 mm from the bottom. Make six peaks with a hypothetical peak height of 8 mm above the middle guide, spaced 10 mm apart peak-to-peak, with the first peak 5 mm from the left edge and the last peak 5 mm from the right edge. Check that the peaks stay inside the square.
Show answer and check
The middle guide is at 30 mm. Peaks rise 8 mm above it to 38 mm, and troughs fall 8 mm below it to 22 mm, so both stay inside the 0 mm to 60 mm height. Place the first peak 5 mm from the left edge and the last peak 5 mm from the right edge; six peaks spaced 10 mm apart peak-to-peak span 5 intervals = 50 mm between the first and last peak, leaving 5 mm at each end, so the wave stays within the 60 mm width.
Why: 30 mm plus 8 mm equals 38 mm, and 30 mm minus 8 mm equals 22 mm; both are between 0 mm and 60 mm. Six peaks at 10 mm peak-to-peak spacing create 5 intervals, so the wave spans 5 times 10 = 50 mm, which is less than the 60 mm square width.
Check: Measure the highest peak from the bottom edge and confirm it is about 38 mm, under 60 mm. Measure the lowest trough and confirm it is about 22 mm, above 0 mm. Count the peaks and confirm six. Measure the first peak's distance from the left edge and the last peak's distance from the right edge and confirm each is about 5 mm, so the wave stays inside the 60 mm width.
Exercise 3
Draw a dot ring with 12 dots on a hypothetical 20 mm radius circle inside a 50 mm square. Connect every second dot. State how many connecting lines you draw and whether the ring fits.
Show answer and check
Connecting every second dot on 12 dots produces two separate 6-point star polygons, because stepping by two around 12 dots splits the dots into two groups of six. Each star polygon has 6 lines, so the total is 6 + 6 = 12 connecting lines. The ring fits inside a 50 mm square because the 20 mm radius is less than the 25 mm half-width.
Why: With 12 dots, stepping by two visits six dots and returns to the start, forming one 6-point star polygon; the remaining six dots form a second 6-point star polygon. That gives 6 + 6 = 12 lines total. The radius 20 mm is less than the 25 mm half-width, so the ring fits.
Check: Count the lines and confirm 12, arranged as two separate 6-point star polygons. Measure the ring diameter, which is 2 times 20 = 40 mm, and confirm it is less than the 50 mm square width.
Exercise 4
Draw four nested contours inside a 60 mm square, starting with a hypothetical 50 mm outer loop and using an even hypothetical gap of 5 mm between loops. State the approximate width of the innermost loop and whether all loops fit.
Show answer and check
Starting from a 50 mm outer loop, each inward step shrinks the width by 10 mm because the gap is 5 mm on each side. Four loops have three gaps between them, so the width shrinks by 3 times 10 = 30 mm. The innermost width is 50 minus 30 = 20 mm, so all four loops fit inside the 60 mm square.
Why: Each gap of 5 mm on both sides reduces the loop width by 10 mm. Four nested loops create three gaps, so the total reduction is 3 times 10 = 30 mm. The innermost width is 50 minus 30 = 20 mm, which is positive and inside the 60 mm square.
Check: Measure the innermost loop width and confirm it is about 20 mm. Count the loops and confirm four, and count the gaps between them to confirm three. Confirm the outer loop is about 50 mm and inside the 60 mm square.
Common mistakes
- Spiral turns are uneven and the line crosses itself. Slow the increase per quarter turn and rotate the paper after each quarter turn.
- Wave peaks drift outside the square boundary. Lower the peak height by 2 mm and redraw the guide lines before continuing.
- Dot ring dots are unevenly spaced. Count the dots first and mark them with a light pencil tick before inking.
- Nested contours touch or merge. Keep a consistent gap and draw each loop completely before starting the next.
Self-check rubric
- Motif stays inside the drawn boundary.
- Repetition is countable and regular.
- Gaps between lines are even enough to check by eye.
- Line quality is controlled and the pen does not tear the paper.
- Lettering, if used, is outside the motif and follows the stated x-height convention.
Questions and answers
Do I need special paper or pens?
No. Plain paper and a pencil plus a fine-tipped pen are enough. Measure your own tools and adjust the hypothetical sizes.
How many turns should the spiral have?
Four to six quarter turns fit a compact square. Count the quarter turns and keep the gap even.
Can I use lettering inside the motif?
Keep lettering outside the motif area. If you use letters, define x-height as baseline to midline and accept that letter styles vary.
How do I know the motif is finished?
The motif is finished when it stays inside the square, the repetition is countable, and the gaps are even enough to check by eye.
