Each corner is a birds-in-the-air unit: a large triangle pointing out to the corner with one small triangle following it, around a background cross and a small centre square.
The duckling is often cut from the duck fabric. Piece the outer half of each corner from four small triangles, then add the large triangle.
Four paws, each a large square with two half-square-triangle claws along each of its two outer sides and a small background square in the outer corner, separated by sashing strips around a centre square.

A magnificent eight-pointed star radiating from the center, created from diamond shapes with background triangles and corner squares.
A traditional 3×3 checkerboard of 2″ squares.
A nine-patch star: plain corners, a centre square, and quarter-square-triangle side units whose triangles form eight points.
Four large half-square triangle units in the corners with their inner halves framing a centre cross of five squares, the edge and centre squares in one fabric and the squares between them in another.
