Sol LeWitt's *Not Straight Brushstrokes In All Directions* is a gouache on paper work that exemplifies the artist's systematic yet expressive approach to mark-making. The composition is densely covered with irregular, curved brushstrokes applied in multiple directions, creating a rhythmic visual energy that fills the picture plane. The interplay of colors and gestural marks reflects LeWitt's exploration of rule-based processes while embracing the inherent variability of the human hand.
