Scholar and author Barbara Brackman will share her revelations about quiltmaking during a lecture, “Clues in the Calico,” at 5:30 p.m. Oct. 26 at the International Quilt Study Center and Museum. The talk is free and open to the public.

“Barbara Brackman is the leading source people turn to for information about dyes and techniques,” said Carolyn Ducey, curator of collections at the museum. “With the host of books she’s written over the past decades, she has developed encyclopedic knowledge. We will learn so much from her presentation.”

The author of “Clues in the Calico,” “Encyclopedia of Pieced Quilt Patterns,” “Quilts from the Civil War” and more, Brackman’s presentation will include a show-and-tell of textiles and quilts from the museum as well as her personal collection.

The lecture is being held in conjunction with the museum’s newest exhibition, “Cheddar Quilts from the Joanna S. Rose Collection,” showing through Feb. 3. Rose is known for her collection of more than 650 red and white quilts which appeared in the 2011 exhibition “Red and White Quilts: Infinite Variety” at the Park Avenue Armory in New York City. Her large collection of antique American orange quilts, known as cheddar quilts, are also on display.

Admission to the museum is free for university students, faculty members, and staff. For more information, visit the quilt museum website.
