Nancy Zieman, who became an unlikely television star through the humblest of shows, “Sewing With Nancy,” which ran for 35 years on public television, died on Nov. 14 at her home in Beaver Dam, Wis. She was 64.

The cause was cancer, said an announcement from Wisconsin Public Television, which produced the show. On Sept. 2, Ms. Zieman wrote a post titled “Time to Say Goodbye” on her website, telling fans that she was retiring and that one of the cancers first diagnosed in 2015 had metastasized.

“I am finding great peace today,” she wrote, “knowing that I can thank you for your many years of dedication, viewership and friendship.”

Nancy Lea Luedtke was born on June 21, 1953, in Neenah, Wis. Her father, Ralph, and her mother, the former Barbara Larson, owned a farm. She learned to sew as a child; for her first sewing project for the local 4-H Club, she made a gathered skirt and fringe scarf.
