While doing a colour-and-composition assignment, I got rather obsessed with drawing hexagons. Couldn’t sleep, so at 3am I figured out how to draw a wall full of hexagons in one-point perspective.
A protractor doesn’t tell you how 30° angles change towards a vanishing point (and anyway, I couldn’t find a protractor at 3am). I used a ruler’s measurements to divide one vertical line into three equal parts, and from then on I relied on the intersections of diagonal lines to find all the edges.
The pattern is made with watercolour pencil, including some brown & black shading in the far corner.
