Retro Radial is an asymmetrical graphic quilt design inspired by retro neon signs. The quilt design of partial concentric circles is pieced with skinny arcs of bright, high contrast fabrics. The quilting adds another layer of interest with blocks of dense stitching in coordinating threads. A final layer of grid stitching in violet thread contrasts with the circular design. Retro Radial is the fifth in a series of high contrast circular designs.
