The first gallery of Thresholds at the Haggerty Museum of Art holds dozens of hand brooms in long rows, bound with ribbons, cords and braids, raw branches from a fallen tree jutting from the top. Made during a participatory workshop at Lynden Sculpture Garden, the sweepers are what Daniel Minter calls a talisman, tool, and object of remembrance. His work keeps returning to the spiritual weight of everyday implements and what it means to cleanse and care for a space.
