- eight star points
- four large triangles
- four squares
The junction between the two star points that would meet at the apex of one of the triangles or a corner of a square is called a 'y-seam' and I have quickly learned that I need much more practice before I attempt this. So, I split both the large triangle and the square into two pieces.
Now, the assembly process changes to:
- stitch together one corner right triangle, one star point, and one side right triangle.
- stitch together two of these right triangles to make a square.
- stitch together the four squares.
The key is to make sure there are four each of the two orientations possible for the right triangle assembled in step 1.
Also - solid pieces need to be cut with an additional seam allowance for the center seam between each solid piece.
Once I worked this out, I was able to sew the top together. It is 'okay'...not 'great'.
