The six Art Quilts are meant to be hung. One is a rendition of a piece of art in another medium (Soft on Klimt), two start with a central "medallion" (Ragtime, Klimt d'Oeil), two make use of curves and another of strips. Optical illusion quilts have been around for at least a century and a half but have a high impact modern look. Like many of the Tradition-Based quilts, some Optical Illusion pieces use a diagonal element to attain cohesiveness.
