For the latest addition to the annual Hygienic festival, artists have to think big.

We mean that literally.

Hygienic Grande focuses on large-format art — including big sculptures and three-dimensional installations — with minimum size of 6 feet in height; a 5-foot-by-5-foot footprint; or a 6-foot-by-6-foot canvas. They will be displayed inside 38 Green St., a site that formerly housed the Monte Cristo Bookshop.

People can bring their artwork for Hygienic Grande between 10 a.m. and 6 p.m. Saturday.

The show is on view to the public starting at 7 p.m. Saturday and then through Feb. 9, with viewing hours noon-7 p.m. Tuesdays through Saturdays and noon to 4 p.m. Sundays.

The idea was proposed by Bill Dumas, who is now coordinating Hygienic Grande. He also started The Screening Room, an independent film festival that remains part of the January Hygienic festival.

Hygienic Grand, opening reception 7-10 p.m. Saturday, 38 Green St., New London; free, donations accepted; show on view through Feb. 9.
