These photos are from the American Museum of Folk Art in New York City, a delightful, pint-sized museum next door to the Museum of Modern Art. This Amish quilt was made in Lancaster, PA using a traditional pattern. There are some great quilts displayed on their website that were not on display at the museum. http://www.folkartmuseum.org/
The picture below is a photo I snapped of a JCrew window display. Prior to being aware of Amish quilts in the style above (although, probably subliminally aware of them), I thought that this would make a great modern quilt design.
