There is more than meets the eye with the work of Fred Sandback. Employing a particularly unique material, acrylic yarn, the artist created architectural works by attaching yarn to surfaces and stretching it taut from floor to ceiling. The open space and surprising dimensions achieved by his pieces allow viewers to interact with them and complete them with their own imagination.

By studying alongside such fellow Minimalists as Robert Morris and Donald Judd, Sandback developed the conceptual, uncluttered method for which he is known.
