This quilt is one of a collection of family heirloom quilts that I've been repairing.
Years ago, I worked with the Illinois quilt documentation days, one of the projects that produced so many statewide data bases and books. I remember some talk about quilts with extra large blocks like this being regional styles in some areas.
The quilt was made in Louisiana. I'm dating it to the 1950s. These photos show colors and prints that are really indicative of that decade.
To paraphrase Dorothy in Oz - Turquoise, salmon, and grey! Oh, my!
