Thread Lines is a series of works completed by covering all or part of the surface with thread-like lines.

This is the sixth work in the series — built on an underlay of purple gradation with white crayon drawing, over which thread-like vertical lines were drawn across the entire surface.

The freehand vertical lines — dense enough to suggest the appearance of pleats or draped fabric — create a compositional contrast with the horizontal crayon lines of the ground beneath.
