There are multiple collections at the IU Museum of Archaeology and Anthropology that contain quilts. Quilts can reflect the creator’s social or cultural identity, which can be easier to identify. Specific color combinations, styles, fabrics, and stitching techniques, give cultures (and eras) their own unique quilting customs. Sometimes there are even regional differences within the same culture.
See below for examples of the kinds that you will find at the IUMAA!
