Sol LeWitt's *Horizontal Brushstrokes (More or Less)* exemplifies the artist's systematic yet subtly organic approach to mark-making, featuring layered bands of gouache applied in rhythmic, horizontal strokes across the paper. The work balances rigid conceptual structure with the inherent variability of the hand, as slight irregularities in pressure and direction lend each stroke a quiet, human imperfection. Rich, opaque color typical of gouache gives the surface a dense, velvety quality that rewards close looking.
