June 28 Aunt Malvena's Chain Variation. It was originally published by the Ladies Art Company(#513) in 1928, with only four half-square triangles along the centre square. Nancy Cabot published it as Indian Mats in the Chicago Tribune in 1935, this time with three half-square triangles along the centre square. She then used the name Navajo, for a slightly different block published in 1936 in the Chicago Tribune. Although she seemed intent on appliqueing the design!
