Object Drawing Lessons
Contour drawing focuses on the outline and internal edges of a subject rather than shading or realistic anatomy. In this lesson you will trace a hand contour, define regions with clear edges, and fill each region with flat color. The goal is edge awareness: seeing where one shape ends and another begins, then committing those edges to paper. You will use a simple convention for hand proportions and a rubric that accepts valid stylistic variation. All measurements are hypothetical examples; measure your own paper and tools before drawing.

Set Up the Plate and Define Your Convention
Prepare a sheet of paper and a pencil. Draw a light rectangular border to define your drawing area. Inside it, sketch a reference hand outline using a simple convention: the palm is a rounded rectangle, four fingers are elongated rounded rectangles of varying length, and the thumb is a shorter rounded rectangle attached at an angle. This convention is not realistic anatomy; it is a checkable shape system that makes edges easy to trace and compare.
Choose a flat-color set of three to five colors. Label each color with a letter (A, B, C, and so on) on a small key at the corner of the page. Decide which regions will receive which color before filling. Keep the color key outside the drawing border so it does not interfere with the contour.
- Draw a light border rectangle measuring, for example, 15 cm by 20 cm. Label this as a hypothetical size and measure your actual paper.
- Sketch the palm as a rounded rectangle about 6 cm wide and 8 cm tall inside the border.
- Add four finger rectangles along the top edge of the palm, each about 2 cm wide and 5 to 7 cm long, spaced evenly.
- Add a thumb rectangle about 2 cm wide and 4 cm long attached to the lower side of the palm at an angle.
- Write a color key with letters A through D and assign one color to each letter.
Trace the Contour and Mark Internal Edges
Tracing means following the outer boundary of each shape with a deliberate line. Use a darker pencil or a fine-tip pen for the contour so it stands out from the light construction sketch. Trace the outer edge of the palm, then each finger, then the thumb. Where shapes meet, draw a clear internal edge line. These internal edges are the boundaries between color regions.
Keep the line quality consistent: a single continuous line for each edge, without sketching back and forth. If you make a mistake, mark it with a small cross and redraw the edge beside it rather than erasing repeatedly, which can smudge the paper. The contour should read as a set of closed or nearly closed shapes so that color filling has clear boundaries.
- Trace the outer boundary of the palm with one continuous line.
- Trace each finger outline, connecting it to the palm edge with a short internal line.
- Trace the thumb outline and its internal edge where it meets the palm.
- Check that every region is bounded by a contour line or the border rectangle.
- Mark any open gaps with a small cross and close them with a short line segment.
Fill Regions with Flat Color
Flat color means one uniform color per region, with no gradients or shading. Fill each bounded region according to your color key. Work from one region to the next, keeping the color inside the contour lines. If a region is small, use a smaller tool or a lighter touch to avoid bleeding over the edge.
After filling, inspect each boundary. A strong contour drawing shows clear edges between colors. If color crosses an edge, correct it by adding a thin line of the neighboring color along the boundary or by trimming the fill with a clean edge. The rubric rewards edge clarity and consistent flat fill, not realistic shading or anatomical accuracy.
- Fill the palm region with color A, staying inside the traced contour.
- Fill each finger region with colors B and C, alternating to make edges visible.
- Fill the thumb region with color D.
- Inspect each boundary and correct any color that crosses a contour line.
- Label each filled region with its color letter in small writing near the edge.
Check Edge Awareness and Consistency
Edge awareness means you can point to each boundary and explain which two regions it separates. Walk through your drawing and name each edge aloud or in writing. Check that every internal edge has a different color on each side, or a clearly marked line if the colors are the same. This makes the contour readable.
Use a simple arithmetic check: count the number of regions and the number of color letters used. If you have four fingers, one palm, and one thumb, that is six regions. If you used four colors, at least two regions share a color, which is acceptable as long as their shared edge is clearly traced. Record your counts in the margin as a check.
- Count the regions: palm, four fingers, thumb equals six regions in the convention.
- Count the color letters used and note which regions share a color.
- Point to each internal edge and name the two regions it separates.
- Verify that no region is left unfilled and no color crosses a contour line.
- Write a one-sentence note describing the clearest edge in your drawing.
Worked example
A student draws a border 12 cm by 18 cm. Inside, they sketch a palm rounded rectangle 5 cm wide and 7 cm tall, four finger rectangles each 1.5 cm wide and 4 to 6 cm long, and a thumb 1.5 cm wide and 3 cm long. They trace all contours with one continuous line per edge, use a color key with letters A, B, C, and fill the palm with A, two fingers with B, two fingers with C, and the thumb with B. Check the region count and color count, and state whether the internal edges are clear.
Worked answer
There are six regions: one palm, four fingers, one thumb. Three color letters are used: A, B, C. The palm uses A, two fingers use B, two fingers use C, and the thumb uses B, so B is shared by three regions. The internal edges are clear if each shared edge is traced with a continuous line and the colors do not cross it. The region count matches the convention, and the color count is three, which is within the suggested range of three to five.
Four practice exercises
Exercise 1
Draw a border 10 cm by 14 cm. Sketch a palm rounded rectangle 4 cm wide and 6 cm tall, three finger rectangles each 1.5 cm wide and 4 cm long, and one thumb 1.5 cm wide and 3 cm long. Trace all contours with one continuous line per edge. Use a color key with letters A and B. Fill the palm with A, the thumb with B, and alternate the three fingers A, B, A. Count the regions and state how many regions use each color.
Show answer and check
There are five regions: one palm, three fingers, one thumb. Color A is used by the palm and two fingers, so three regions use A. Color B is used by the thumb and one finger, so two regions use B.
Why: The convention gives one palm, three fingers, and one thumb, totaling five regions. The fill plan assigns A to the palm and two fingers, and B to the thumb and one finger. Counting confirms three A regions and two B regions.
Check: Count the regions on the drawing and compare to five. Count the regions filled with A and with B, and verify the totals are three and two. Check that each internal edge is traced and no color crosses it.
Exercise 2
A student sketches a palm 5 cm wide and 7 cm tall, four fingers each 1.5 cm wide and 5 cm long, and a thumb 1.5 cm wide and 3 cm long inside a 12 cm by 18 cm border. They trace the outer contour but leave a 1 cm gap between the first finger and the palm. They fill the palm with color A and the first finger with color B, and the color crosses the gap. Describe the mistake and the fix, then state how many regions should be closed after the fix.
Show answer and check
The mistake is an open contour gap that lets color cross between the palm and the first finger. The fix is to draw a short line segment closing the gap and re-trace the internal edge, then trim the color so each region is separate. After the fix, six regions should be closed: palm, four fingers, thumb.
Why: An open gap means the region is not bounded, so flat fill cannot stay inside one region. Closing the gap with a short segment and re-tracing the internal edge restores the boundary. The convention has six regions total, so all six should be closed after the fix.
Check: Locate the gap and confirm it is closed by a line segment. Check that the palm and first finger have separate flat colors with no crossing. Count the closed regions and verify the total is six.
Exercise 3
Draw a border 15 cm by 20 cm. Use the convention: palm 6 cm by 8 cm, four fingers 2 cm wide and 5 to 7 cm long, thumb 2 cm wide and 4 cm long. Trace all contours. Use a color key with letters A, B, C, D. Fill the palm with A, the thumb with D, and assign B and C to the four fingers so that no two adjacent fingers share the same color. State the color assignment and count how many regions use each color.
Show answer and check
One valid assignment is: finger 1 B, finger 2 C, finger 3 B, finger 4 C. The palm uses A, the thumb uses D. Color A is used by one region, B by two fingers, C by two fingers, and D by one region.
Why: Adjacent fingers must not share a color, so alternating B and C across four fingers satisfies the rule. The palm and thumb use separate letters A and D. Counting gives one A region, two B regions, two C regions, and one D region.
Check: Check each pair of adjacent fingers and confirm they have different letters. Count the regions per color and verify the totals are one, two, two, and one. Confirm every region is closed and filled with flat color.
Exercise 4
A student draws a hand contour with five regions and uses three colors: A, B, C. They claim every internal edge is clear because each edge has a different color on each side. There are four internal edges in their drawing. Is the claim possible? Explain using a simple count, and state one check they can perform.
Show answer and check
The claim is possible only if the color arrangement allows each of the four internal edges to separate two different colors. With three colors and five regions, some colors must repeat, so the student must verify each edge individually. A simple check is to point to each internal edge and name the two colors on either side; if any edge has the same color on both sides, the claim fails for that edge.
Why: Five regions and three colors means at least two regions share a color, so a repeated color does not automatically break the claim, but each internal edge must still be checked. Four internal edges require four pairwise color differences. The count alone does not prove the claim; the edge-by-edge check does.
Check: List the four internal edges and write the two colors on each side. Confirm that no edge has the same letter on both sides. If all four edges pass, the claim holds for this drawing.
Common mistakes
- Sketching the contour with many short back-and-forth strokes, which creates a fuzzy edge. Redraw the edge with one continuous deliberate line beside the fuzzy one, then mark the old line with a small cross.
- Filling color across an internal edge so two regions merge visually. Re-trace the internal edge with a darker line and trim the fill on each side so the boundary is clear.
- Using gradients or shading inside a region instead of flat color. Choose one color per region and fill uniformly; reserve any darker marks for the contour line only.
- Leaving a gap in the contour so a region is not closed. Locate the gap, draw a short line segment to close it, and confirm the region is bounded before filling.
Self-check rubric
- Contour lines are continuous and deliberate, with no fuzzy back-and-forth sketching on the final edges.
- Every region is closed by a contour line or the border rectangle, with no open gaps.
- Each region is filled with one flat color, and no color crosses an internal edge.
- The color key lists every letter used and matches the filled regions.
- Internal edges are traceable: each edge separates two named regions, even if they share a color.
- The drawing follows the stated convention or a clearly labeled alternative convention, and valid stylistic variations are accepted.
Questions and answers
Do I need realistic hand anatomy for this lesson?
No. The lesson uses a simple rounded-rectangle convention for the palm, fingers, and thumb. The focus is contour tracing and flat color fill, not anatomical accuracy.
Can I use more than four colors?
Yes, as long as each region has one flat color and the color key lists every letter you use. More colors can make edges easier to see, but keep the key simple enough to check.
What if my hand outline does not match the example sizes?
The sizes given are hypothetical examples. Measure your own paper and adjust the rectangle dimensions so the hand fits inside the border with space around it.
How do I know my contour is clear enough?
Point to each internal edge and name the two regions it separates. If you can do that without confusion, the contour is clear. The rubric also checks that every region is closed and filled with flat color.
