While Christmastime for some residents means large Santa decorations and enough lights to double an energy bill, others turn their attention to the inside of their house as part of local holiday home tours.

The home tours also represent a more festive chance to give back, one of the major draws for Glenda Cohn. The Brentwood resident is participating in this weekend’s Liberty Union High School District Holiday Home Tour, which benefits the district’s educational foundation.

“I don’t mind doing fundraisers for any of the schools locally, so that’s what I enjoy,” Cohn said. “I like the holiday season, I like to decorate my house, I like to bring people out and just be festive.”

Cohn said she enjoys decking out her Colonial-style house with decorations appropriate to that time period, taking tour participants to a different era. She said she toyed with the notion of asking a friend to dress in colonial garb, but she’s keeping that idea in reserve for now.

The tour will start at Cohn’s Hanna Nicole Vineyards, 6700 Balfour Road, at noon on Saturday. The festivities also feature a silent auction, door prize drawings and live entertainment. Tickets are $25 in advance or $30 at the door. For tickets and more information, visit educationwins.org.

On Sunday, six Discovery Bay residents show off their décor as part of the Discovery Bay Holiday Home Tour, which benefits the Discovery Bay Community Presbyterian Church’s community projects.

Discovery Bay resident Tina Duncan said this will be her first year participating in the event after she helped out over the past six or seven years. She enjoys the challenge of thinking about Christmas shortly after the last trick-or-treaters stop by. “It’s a really well-run event, and I love to see houses that are decorated for the holidays,” Duncan said.

She has toured houses in past events to gather ideas about how to decorate her own house. Duncan, whose grandfather used to dress up as Santa for mall appearances, said one of her favorite decorations is a special old-fashioned doll of St. Nick on her kitchen table. Duncan also treasures her nativity scene, something she and her daughter contribute to every year.

Tour participants will meet at the church, 1900 Willow Lake Road, at 12:30 p.m. Tickets are $20. For more information, call 925-513-1939 or 925-634-0184.

The Antioch Women’s Club holds its 56th Antioch Holiday Home Tour on Dec. 12 in Rivertown. Five houses and three businesses will participate in the tour.

One of the historic houses belongs to Connie Komar. This is the second time Komar has done this, though she’s been involved with the Women’s Club for four years. “I love to decorate. I go overboard,” Komar said. “It was nice to have people come in and look and appreciate it.”

Komar said her house is more than 100 years old, so she has lavished it with antiques to give it an old-fashioned feel.

The tour, which runs from noon to 4 p.m., is followed by a reception from 2:30 p.m. to 5 p.m. at Veterans Memorial Hall at Sixth and E streets. Tour goers can start wherever they wish, but participant Liese McCause said Teazz Salon, 606 W. Second St., is a good starting point. Tickets are $25 and proceeds go to the Women’s Club efforts for scholarships for local high school students.

For information, call McCause at 925-777-1831 or Komar at 925-522-8663.
