Step 6. Strip-piecing refers to rotary cut strips of specified widths being sewn together on long edges to make strip-pieced units.

Step 7. When creating strip-pieced patchwork, it is wise to press seam allowances in opposite directions so that long units can be layered for cutting quickly and will later be easy to sew. In the photo, seam allowances were pressed toward the light floral fabric on both strips.

Step 8. Strip-pieced units are cut apart, segments positioned to make patchwork, and sewn together.
