Create the illusion of curves with this Curvy Log Cabin Trim Tool. Sew four blocks together to “piece” a circle. Mark the wrong side of the center square through the holes on the ruler to ensure a perfect seam allowance. Then sew a round – two narrow and two wide and trim. Add two more rounds to complete a perfect 8” finished block. The cutting requirements for the center square and the narrow and wide strips are printed right on the ruler. Combine these blocks with the original Log Cabin Trim Tool (CGRJAW1) for unlimited design possibilities.
