Wejchert’s work sits at the intersection of several abstract art movements, including constructivism, kinetic art, and op-art. Her practice reflects an interest in formal structures, many of her pieces also convey a strong sense of movement, and the repetition of forms almost creates optical illusions.

Texture played a central role in her approach. She frequently experimented with materials and colour, working with mediums such as stainless steel and plexiglass to explore new visual effects.

Across all formats, her work is united by a strong rhythmic sensibility that gives it structure and movement without relying on literal motion. The repetition of forms has been said by some scholars to have a musical feeling.

Her metal sculptures have been described by Professor Ann O. Crookshank as “mysterious maze-like tentacled objects,” works are intricate while maintaining a clear, deliberate structure.
