Block 1: twisted pleats – Textured 4-patch quilt
This technique looks confusing, but is not difficult to sew. These alternating pleats are just created by marking pleats at the top, and the bottom. The pleats at the bottom should be marked directly in between the marked top pleats. When you sew the pleats, it looks like the fabric is folded in on itself and intertwined together.
