1. Referring to Diagram 1, sew together four squares, stopping and starting each seam at marked dots, 1/4" from corners.
2. Matching dots, sew another square to one edge of pieced unit (Diagram 2).
3. Repeat Step 2, joining remaining square to unsewn edge of pieced unit, leaving a 1-1/2" opening along one side for turning, to make a cube (Diagram 3).
4. Turn cube right side out. Stuff with fiberfill to desired firmness, working fiberfill into corners. Using quilting thread or double thread, securely hand-sew opening together to complete the block.
