Appalachian Spring by Judy Martin is included in her Singular Stars book. It was part of a special exhibit of her quilts at AQS QuiltWeek Spring Paducah 2019. The quilt is a strip pieced Lone Star quilt, but somehow Judy managed to make the traditionally "straight" lines of the quilt appear "curved," giving it an almost flower-like shape in the center. Can you see how she did it?
Hint: the strips are part of the fabric. Look at the detail picture below.
