Available in 2 sizes: 6″ and 12″. More than 80 different blocks and borders. Now you can create a whole collection of new blocks and, with a little imagination, you can even create your own unique block. Each ruler is designed to allow mixing and matching. Each piece includes the seam allowance, has the points removed to enable easy line up and every piece you cut will be the same. This will make your blocks accurate and your quilts something to admire. Each set has instructions on how to make the three feature blocks.
