After 20 years, the Second Congregational Church will hold its final benefit quilt show and luncheon on March 1. “It’s been a great tradition, but we decided it’s run its course,” said organizer Annette Sawchuck. She said it’s been increasingly difficult to find quilts to display “because we’ve never had the same one twice.” More than 1,000 quilts have been displayed over the years and $39,000 donated to charity, she said. All proceeds benefit the Spark Center in Mattapan, which serves children with complicated medical issues and significant family or social problems, she said. Tickets to this year’s “grand finale” are available for $15 by sending a self-addressed, stamped envelope, and check payable to Second Congregational Church, to 100 Pond St. #16, Cohasset 02025. Reservations for groups of six or more are accepted for specific luncheon seatings by contacting DeeDee Perry at 781-383-9474.
