Object Drawing Lessons
Drawing hairstyles accurately becomes manageable when you map the outline and major strand groups onto a proportion grid. This lesson teaches a cell-by-cell method: you define a grid over a reference hairstyle, record which cells contain outline segments and strand landmarks, then reproduce those cells on a blank matching grid. The approach separates proportion from texture, so you can focus on shape and placement before adding freehand detail. All measurements are simple and checkable; any numerical grid sizes are hypothetical examples you can adjust after measuring your own paper and reference.

Set up a proportion grid and define the convention
A proportion grid divides the drawing area into equal squares. Choose a grid size that fits your paper and reference; for example, a hypothetical 8 by 10 grid with 2 cm squares gives a 16 cm by 20 cm drawing area. Measure your actual paper and reference before committing to numbers. Label columns left to right with letters and rows top to bottom with numbers so every cell has a unique name such as C4.
Define a clear convention for what counts as a mapped feature. For this method, a cell is marked if the hairstyle outline passes through it or if a major strand group begins, ends, or changes direction inside it. Minor texture lines are not mapped. Use two symbols: an O for outline cells and an S for strand-landmark cells. This convention allows valid alternatives because different artists may judge borderline cells differently; the rubric rewards consistent, documented choices rather than a single universal answer.
- Measure your paper and reference; record the drawing area in centimetres.
- Divide the area into equal squares and label columns and rows.
- Trace or visually follow the hairstyle outline and mark every cell it enters with O.
- Mark cells where major strand groups start, end, or change direction with S.
- Write a one-line key explaining your O and S symbols and any borderline decisions.
Map the reference hairstyle cell by cell
Work through the reference systematically. Start at the top-left cell and scan row by row. For each cell, ask two questions: does the outline pass through this cell, and does a major strand landmark occur here? Record O, S, both, or leave blank. Keep a tally of marked cells so you can check completeness later.
Pay attention to the hairline and the outer silhouette. The hairline is often a curve that crosses several cells; note where it enters and exits each cell. The outer silhouette may include volume above the head, sides that fall beside the face, and ends that stop at a shoulder line. Mark these boundaries precisely. If a strand group splits, mark the split cell with S and note the two directions in your key.
- Scan row by row from top-left to bottom-right.
- Mark O where the outline enters a cell; mark S where a strand group starts, ends, or changes direction.
- Record borderline cells and your reason in a short note.
- Count marked cells and compare with a second pass to catch omissions.
Reproduce the map on a blank matching grid
Place the blank matching grid beside your reference map. Copy cell by cell, not outline by outline. For each marked cell, reproduce the segment or landmark in the corresponding position. Use light pencil first so you can adjust. Check alignment by comparing the row and column labels, not by eyeballing the whole shape.
After copying all marked cells, connect outline segments smoothly and add only the strand landmarks you recorded. Do not add freehand texture yet; this method excludes freehand hair texture and pen-and-ink stroke practice. The goal is proportion and placement. If a copied cell looks wrong, compare its position relative to neighbouring marked cells and correct it before moving on.
- Copy marked cells in row order, matching labels exactly.
- Connect outline segments within and across cells.
- Add strand landmarks only where S was recorded.
- Check each row against the reference map before proceeding to the next.
Check proportion and strand placement with simple arithmetic
Use checkable arithmetic to verify proportion. Count the number of cells the hairstyle spans horizontally and vertically. For example, if the outline spans columns B to F, that is 5 columns; if it spans rows 2 to 7, that is 6 rows. Compare these counts with your copy. A mismatch of more than one cell in either direction suggests a proportion error worth correcting.
For strand placement, count S cells per row and compare with the reference. If the reference has three S cells in row 3 and your copy has two, locate the missing landmark. Keep units consistent: use cell counts, not centimetres, for these checks. Record your counts in a small table so the check is repeatable.
- Count horizontal span in columns and vertical span in rows for reference and copy.
- Compare counts; investigate differences greater than one cell.
- Count S cells per row and compare.
- Record counts in a table with columns for row, reference S count, and copy S count.
Worked example
A reference hairstyle on an 8 by 10 grid has outline cells spanning columns B to F (5 columns) and rows 2 to 7 (6 rows). Row 3 contains three S cells. A copy spans columns B to E (4 columns) and rows 2 to 7 (6 rows), with two S cells in row 3. Identify the likely errors and state a correction.
Worked answer
The copy is one column too narrow horizontally and missing one strand landmark in row 3. Check column F cells for omitted outline segments and compare row 3 S positions with the reference. Correct by adding the missing outline cell in column F and the missing S landmark, then recount spans and S cells to confirm 5 columns, 6 rows, and three S cells in row 3.
Four practice exercises
Exercise 1
On a 6 by 8 grid, a hairstyle outline spans columns A to D (4 columns) and rows 1 to 5 (5 rows). Row 2 has two S cells. Your copy spans columns A to D and rows 1 to 6, with two S cells in row 2. What is the likely error and how do you check it?
Show answer and check
The copy is one row too tall vertically. Check row 6 for outline cells that should not be marked, compare row spans (reference 5 rows, copy 6 rows), and remove any incorrect row 6 marks. Recount to confirm 5 rows.
Why: Horizontal span matches at 4 columns, and S count matches at two in row 2. The only mismatch is vertical span, so the error is an extra row.
Check: Count rows from top to bottom for both reference and copy; confirm both span 5 rows after correction.
Exercise 2
A reference map has O marks in cells B2, B3, C3, C4, and D4, and S marks in C3 and D4. Describe how you would copy these cells onto a blank matching grid and what you would check after copying.
Show answer and check
Copy each cell in row order: B2 O, B3 O, C3 O and S, C4 O, D4 O and S. After copying, check that each labelled cell contains the same symbol and that connected outline segments run from B2 through B3 to C3 to C4 to D4. Count O marks (5) and S marks (2) to confirm completeness.
Why: Row-order copying prevents skipping cells, and symbol counts provide a simple completeness check.
Check: Compare symbol counts per cell and total O and S counts with the reference; verify connected segments cross cell boundaries at the same labelled positions.
Exercise 3
You are mapping a hairstyle with a hairline curve that enters cell C2, exits at C3, and re-enters at D3. How would you mark these cells, and how would you document a borderline decision about whether the curve touches D2?
Show answer and check
Mark C2, C3, and D3 with O. For D2, decide whether any part of the curve enters the cell; if it does, mark O and note the reason in your key. If it does not, leave D2 blank and note that the curve passes close but does not enter. Either choice is valid if documented and applied consistently.
Why: The convention marks a cell when the outline enters it. Borderline cases require a documented decision so the map remains consistent.
Check: Review the key note and confirm the same borderline rule is applied to similar cells elsewhere in the map.
Exercise 4
A copy has three S cells in row 4, but the reference has four. The horizontal span matches at 5 columns and the vertical span matches at 6 rows. What steps do you take to find and fix the missing landmark?
Show answer and check
Compare row 4 cell by cell between reference and copy. Identify the labelled cell where the reference has S but the copy does not. Check whether the strand group start, end, or direction change was omitted, add the S mark, and recount row 4 to confirm four S cells.
Why: Spans match, so proportion is likely correct; the mismatch is isolated to strand landmarks in one row. Cell-by-cell comparison locates the omission.
Check: Recount S cells in row 4 and compare with the reference count of four; also verify neighbouring rows are unchanged.
Common mistakes
- Marking every texture line as a strand landmark, which clutters the map. Map only major strand groups that start, end, or change direction; leave minor texture unmapped.
- Copying the outline as one continuous line instead of cell by cell. Work in row order and match each marked cell to its labelled position before connecting segments.
- Using inconsistent grid sizes between reference and copy. Measure both grids and confirm equal square dimensions; record the size in centimetres.
- Ignoring borderline cells and leaving gaps in the outline. Document borderline decisions in your key and mark the cell if any part of the outline enters it.
Self-check rubric

- Convention for O and S symbols is stated and applied consistently.
- Outline cells are mapped without unexplained gaps.
- Strand landmarks are limited to major groups and recorded accurately.
- Copy matches reference span counts within one cell horizontally and vertically.
- S cell counts per row match the reference or differences are explained.
- Borderline decisions are documented and consistent.
- Valid alternative mappings are accepted when the convention is clear and applied uniformly.
Questions and answers
Do I need a specific grid size?
No. Choose a size that fits your paper and reference, measure it, and keep it consistent between reference and copy. Any numerical example here is hypothetical.
What if two artists mark different cells?
That is acceptable if each documents the convention and applies it consistently. The rubric rewards consistent, explained choices rather than a single universal map.
Can I add hair texture after mapping?
This method excludes freehand texture practice. Complete the mapped outline and strand landmarks first; texture is a separate skill.
How do I know my proportion is correct?
Compare horizontal and vertical span counts in cells between reference and copy. A difference of more than one cell signals a proportion error to investigate.
