Chain Gang offers three different 12-pattern sets: twelve different chains, twelve different flowers, and twelve different paper-pieced star blocks. Each block finishes at 12 inches. The background of the blocks can be black or white or off-white or any other desired color of fabric. The beauty of the Chain Gang block-of-the-month is that because of the wide variety of blocks, the setting options are enormous -- the blocks can be set together or separately, on point or straight set. Just think: you can be your own designer with Chain Gang! Various setting options are included in Month 12 of each series.
