Pen and Ink Tree Drawing: Hatching Bark and Stipple Foliage

Object Drawing Lessons

Pen and ink rewards deliberate marks. This lesson teaches a repeatable approach to drawing a tree: establish a clear contour, build bark with cross-hatching, render foliage with stipple, and control line weight to suggest light and depth. You will work from a simple scaffold and use checkable steps. All marks are made with a pen; no pencil shading is used. The convention for foliage is that stipple density increases where the canopy is darker, and decreases where light strikes. Bark hatching follows the trunk's vertical flow, with cross-hatch added on the shadow side. Line weight is varied by pressure and by overlapping strokes, not by switching tools. Measure your actual pen and paper if you record sizes; any numbers here are hypothetical examples.

Contour line and trunk structure

Begin with a single contour line that describes the trunk's taper and the main branches. Keep the line continuous where possible; breaks can suggest bark texture but should not obscure the tree's silhouette. Decide the light direction before drawing: place the shadow side on the opposite side of the trunk from the light.

Draw the trunk as two converging lines rather than a rectangle. A hypothetical trunk width of 3 cm at the base tapering to 1.5 cm at the first branch gives a clear taper. Check that the branch angles alternate left and right and that no branch crosses the trunk without a clear junction.

1. Mark the ground line and the trunk base width.
2. Draw the left trunk edge upward with a slight curve.
3. Draw the right trunk edge, tapering toward the first branch.
4. Add two or three main branches, alternating sides.
5. Check the silhouette by tracing it with your finger; adjust any ambiguous junction.

Cross-hatch bark

Bark is rendered with hatching that follows the trunk's vertical direction, then cross-hatching on the shadow side. Keep hatch spacing consistent: a hypothetical spacing of 2 mm between lines is easy to check. On the lit side, use single-direction hatching only; on the shadow side, add a second set of lines at roughly 45 degrees to the first.

Do not cover the entire trunk with cross-hatch. Leave the lit edge with sparse or no hatching so the contour remains readable. Check density by counting lines in a 1 cm square: the shadow side should have more lines than the lit side.

1. Draw vertical hatch lines from the base to the first branch on the shadow side.
2. Add a second set of diagonal lines crossing the vertical hatch on the shadow side only.
3. Leave the lit side with sparse vertical hatch or none.
4. Check that hatch lines stop before the contour edge on the lit side.
5. Compare line counts in a 1 cm square on each side to confirm density difference.

Stipple foliage

Foliage is built from dots, not outlines. Define the canopy shape with a few light contour marks, then fill with stipple. Denser dots create shadow; sparser dots create light. Work in small patches so you can judge density before committing.

Use a hypothetical rule: in a 1 cm square, a shadow patch has about 30 dots and a light patch about 10 dots. This is a checkable target, not a standard. Keep dot size consistent by touching the pen briefly to the paper. Avoid rows of dots; vary placement to avoid patterns.

1. Lightly mark the canopy outline with short contour strokes.
2. Stipple the shadow side first, using denser dots.
3. Stipple the lit side with sparser dots.
4. Leave gaps at the canopy edge to suggest leaf clusters.
5. Check density by counting dots in two 1 cm squares, one shadow and one light.

Line weight and final checks

Line weight is controlled by pressure and overlap. Use a heavier line for the trunk contour and lighter lines for branches and foliage contour. Overlapping strokes can thicken a line without changing tools. Keep the heaviest lines on the shadow side and the lightest on the lit side.

Before finishing, check three things: the silhouette reads as a tree, the bark hatch follows the trunk, and the foliage density matches the light direction. If any check fails, adjust the relevant area rather than adding more marks everywhere.

1. Trace the trunk contour with a heavier line on the shadow side.
2. Lighten branch contours by using less pressure.
3. Check that foliage stipple density is higher on the shadow side.
4. Confirm that no hatch lines cross the lit contour edge.
5. Make final adjustments only in the area that failed the check.

Worked example

Draw a tree with a trunk base width of 3 cm tapering to 1.5 cm at the first branch. Light comes from the left. Use vertical hatch on the lit side and cross-hatch on the shadow side. Stipple the canopy with denser dots on the right side. Check dot counts in two 1 cm squares.

Four practice exercises

Common mistakes

• Outlining every leaf or foliage cluster with a continuous line. Remove or avoid outlines; use stipple density to define foliage shape instead.
• Applying cross-hatch evenly across the whole trunk. Restrict cross-hatch to the shadow side and leave the lit side sparse.
• Using rows of evenly spaced dots for foliage. Vary dot placement and count dots in a 1 cm square to check density.
• Making all lines the same weight. Use heavier pressure on the shadow contour and lighter pressure on branches and foliage.

Self-check rubric

• Silhouette reads as a tree with a clear trunk taper and alternating branches.
• Bark hatch follows the trunk direction; cross-hatch appears only on the shadow side.
• Foliage is rendered with stipple, not outlines; density is higher on the shadow side.
• Line weight is heavier on the shadow contour and lighter on branches and foliage.
• Checks are documented: taper measured, hatch direction confirmed, dot counts recorded.
