Using acrylic yarn, Fred Sandback made Minimalist sculptures that impress themselves upon the eye as objects with volume and mass. Sandback’s “leaning” works, in which lengths of yarn are suspended diagonally between wall and floor, appear to fundamentally alter a space, while his floor-to-ceiling screens, varying in scale to engage the potential of each space, possess an architectural presence. The subtlety of the artist’s choice of material allows the spaces between the lines to become as visible as the lines themselves.
