Object Drawing Lessons

This lesson teaches a repeatable method for drawing pointed mermaid scales on nail-shaped templates. You will use a simple convention: each scale is a pointed oval with a curved top and a V-shaped bottom, and rows alternate offset by half a scale width. The goal is even spacing and clean overlaps, not a single perfect style. Work on paper templates first, then transfer the sequence to nails. All measurements are hypothetical examples; measure your own template and tools before marking.

Practice materials: Printable downloads are not available for this lesson yet. Use the instructions and four exercises below.

Set up the template and scale convention

Draw or print a nail-shaped outline about 20 mm long and 12 mm wide at the tip. Mark a baseline 2 mm above the cuticle edge, a midline 10 mm above the baseline, and a vertical centerline down the middle of the template. These numbers are hypothetical; adjust to your template. The scale convention: a pointed oval whose top is a shallow curve and whose bottom is a V. Each scale is about 4 mm wide and 5 mm tall in this example.

Lightly mark row guides every 3 mm from the baseline to the tip. Row 1 starts at the baseline, row 2 is offset half a scale width to the right, and so on. Keep the pointed tips facing the nail tip.

  1. Measure your template length and width; write the values at the top.
  2. Mark the baseline and midline with a light pencil.
  3. Draw horizontal row guides at your chosen spacing.
  4. Draw one practice scale on scrap paper to confirm the pointed-oval shape.

Place pointed scales row by row

Start at the baseline. Place the first scale centered on the vertical centerline, then add scales left and right with a small gap of about 0.5 mm. In row 2, shift the first scale half a width to the right so its point sits between two scales below. Continue alternating. Stop when the row reaches the nail edges; partial scales at the edges are acceptable if the point stays inside the outline.

Check overlap: each scale's V should sit slightly over the curved top of the scale below, about 1 mm. If the V floats above, lower the row; if it covers too much, raise it.

  1. Draw row 1 from the center outward.
  2. Offset row 2 by half a scale width.
  3. Alternate offsets for each new row.
  4. Trim or omit edge scales that cross the nail outline.

Refine spacing and add the highlight plan

After drawing all rows, check that no two points in the same row touch and that gaps are consistent. Erase and redraw any scale that is more than 1 mm off. For the top-coat highlight, plan a thin curved line along the upper left of each scale, leaving the V clear. This is a drawing plan, not a product claim; test any top coat on scrap first.

Use a simple rubric: even row spacing, consistent scale size, correct half-offset, clean points, and a highlight that follows the curve without covering the V.

  1. Compare gaps in each row; adjust outliers.
  2. Mark highlight lines lightly on every third scale.
  3. Review against the rubric before finalizing.

Worked example

A template is 18 mm long and 10 mm wide. Scale width is 3 mm, height 4 mm, row spacing 2.5 mm. How many full rows fit from baseline to tip, and how many scales fit across the widest row?

Worked answer

Full rows: 18 divided by 2.5 equals 7.2, so 7 full rows fit. Scales across: 10 divided by 3 equals 3.3, so 3 full scales fit with edge space.

Four practice exercises

Exercise 1

A nail template is 15 mm long with row spacing 3 mm. How many full rows fit?

Show answer and check

5 full rows.

Why: 15 divided by 3 equals 5, so five complete rows fit exactly.

Check: Multiply 5 rows by 3 mm to get 15 mm, matching the template length.

Exercise 2

A row is 12 mm wide and each scale is 4 mm wide with 0.5 mm gaps. How many full scales fit, and how much space is left?

Show answer and check

2 full scales fit, with 3.5 mm of space left.

Why: Two scales plus one gap use 4 + 0.5 + 4 = 8.5 mm. A third scale would need another 0.5 mm gap plus 4 mm, totaling 8.5 + 0.5 + 4 = 13 mm, which exceeds 12 mm. So only two scales fit, and 12 - 8.5 = 3.5 mm remains.

Check: Add the widths and the single gap between two scales: 4 + 0.5 + 4 = 8.5 mm, which is less than 12 mm. Adding a third scale and its gap gives 8.5 + 0.5 + 4 = 13 mm, which is more than 12 mm, confirming only two scales fit.

Exercise 3

Row 1 has scales centered at 3 mm, 7 mm, and 11 mm. Where should the first scale of row 2 start if the offset is half a 4 mm scale?

Show answer and check

At 5 mm.

Why: Half of 4 mm is 2 mm; adding 2 mm to the first center at 3 mm gives 5 mm.

Check: The 5 mm center sits halfway between 3 mm and 7 mm, confirming the half-offset.

Exercise 4

A scale is 5 mm tall and overlaps the scale below by 1 mm. If row 1 starts at 0 mm, where does row 2 start?

Show answer and check

Row 2 starts at 4 mm.

Why: The next row begins 5 mm minus 1 mm overlap above the previous start, so 0 + 4 = 4 mm.

Check: Row 1 top is at 5 mm; row 2 start at 4 mm leaves a 1 mm overlap, matching the plan.

Questions and answers

Do I need a specific nail length?

No. Measure your template and choose a scale size that fits at least three scales across the widest part.

Can I use different scale shapes?

Yes. The rubric allows any pointed scale with a curved top and a V bottom, as long as spacing and offset are consistent.

How many rows should I draw?

Draw as many complete rows as fit between baseline and tip; partial rows at the tip are fine if points stay inside.

What if my hand is unsteady?

Draw larger scales first, then reduce size only after row spacing is even.
