The Housatonic Valley Association will hold its biggest fundraiser, its 19th annual auction Dec. 6 at Bryan Memorial Town Hall in Washington.

Fashion designer and HVA board member Diane von Furstenberg of New Milford is asking area businesses and residents to join her in donating one-of-a-kind experiences, vacation homes, artwork, jewelry, home furnishings, Broadway and sporting event tickets, fine dining gift certificates, fashions, wines and more to the auction.

Ms. von Furstenberg's friends have also agreed to locate one-of-a-kind donations and to co-chair the festivities.

They are fellow board member and actress Christine Baranski, fashion designer and area resident Oscar de la Renta and his wife Annette, fashion marketing consultant Hamilton South and Travel and Leisure Magazine editor-in-chief Nancy Novogrod.

Festivities will include a silent auction and champagne reception, with music by Miles of Swing, at 1 p.m., and a live auction with celebrity auctioneer Tim Luke of HGTV's "Treasure in the Attic" at 3 p.m.

Tickets are $50 for general admission. Patron tickets are $150 and include reserved auction seating and a choice of a pre-auction brunch or a twilight supper hosted by the GW Tavern in Washington Depot.

Honorary Committee memberships are available with the silver ($250 per person), gold ($500 per person), diamond ($1,000 per person) and platinum ($2,500 per person) levels. Donors will receive special seating.

All donors at the $150 and higher levels will be recognized in the auction program.

Patrons at the $250 level and above are entitled to bring one item to be appraised by Mr. Luke Dec. 5 from 2 to 4 p.m.

Proceeds from the event will support projects to protect the Housatonic River and its 2,000-square-mile watershed that includes 83 towns from Pittsfield, Massachusetts through the Berkshires, eastern New York State and western Connecticut to Long Island Sound.
