Create the illusion of curves with this 4 inch version of our popular Curvy Log Cabin Trim Tool. Sew a round – two narrow strips and two wide strips and trim. Add two more rounds to complete a perfect four inch finished block. Sew four blocks together to “piece” a circle which finishes to eight inches. Combine these blocks with traditional 4 inch log cabin blocks (Item CGRJAW4MN) for unlimited design potential.
