Cross hatching creating a grid-like texture instead of form
“My cross-hatching looks like a flat chain-link fence instead of curved form.”
What is happening
Hatching lines cross each other at rigid perpendicular ninety-degree angles. The surface appears flat and patterned like graph paper rather than curving around a three-dimensional volume.
Cross-hatching lines should follow the cross-contour curves of the form they describe. Intersecting lines at exact right angles creates an optical flat grid that destroys the illusion of volume.
The 30-second test
Look at your cross-hatch marks with a magnifying glass or phone zoom; if the lines form sharp little squares, you have built a flat grid.
How to fix it
- Avoid adding any further perpendicular strokes over the affected area.
- Apply new hatch strokes that follow the wrapping cross-contour of the cylindrical or spherical form.
- Keep intersections at acute, oblique angles rather than strict ninety-degree corners.
- Deepen the shadow core to drown out the most distracting grid intersections.
Can it be saved? Partly
You can soften the grid look by glazing cross-contour lines or deepening tones toward solid shadow, though severe grids remain slightly visible.
Drill: Cross-contour sphere hatching
About 20 minutes. You need:
- sketchbook paper
- 0.3mm fineliner
Draw a sphere outline. Shade the shadow side with curved lines that wrap like latitude lines around a globe. Add a second layer at an acute angle following the form curve, avoiding perpendicular grids.
