Overlapping triangular planes

Abstraction Based on Sails VI gathers blue, grey and ochre triangles into an upright cluster on a pale ground. Some areas carry fine patterns while others remain flat. The changing directions suggest a structure assembled from many separate pieces, with the surrounding blank space making its outer edge particularly clear.

A smaller cluster with open edges

Abstraction Based on Sails I places patterned green, grey and pale pink areas within a looser angular arrangement. A small circular form interrupts the triangles near one side. Compare the balance of filled and empty areas with the denser sail compositions, where more overlapping planes occupy the central space.

Rounded shapes replacing the angles

Abstraction Based on Flower Forms I spreads broad blue, green, yellow and dark forms across a light background. Small scattered marks sit between the larger areas. The flower-based title offers a starting point, but the image leaves the relationship between individual shapes open rather than describing a single identifiable bloom.

The geometric abstract collection develops the sail series’ angular relationships, while the wider abstract collection includes softer, less clearly bounded forms closer to the flower-based works.
