1- Fold fabric in fourths.
2- Square up edge of fabric and cut strips needed. Leave strips as close together as possible.
3- Turn the cutting board not the fabric for this step. Place the acrylic ruler on all strips and square up the edges. Cut the size squares or rectangles needed. Note: For this tutorial I cut two strips. Cut as many strips as needed or that the ruler will cover. Each strip yields four pieces per cut. My example shows one cut through two strips yielded eight squares.
That's all there is to it. I'm off to my cutting table to whack more fabric.
