The design you are wanting is known by many different names.
You don't even need a pattern. You can draw your own. In which case it helps to know where you are cutting by measuring on the outside edge - like registration marks in sewing/embroidery.
ex:
1st cut: 2" up from Right lower corner to 4" down from Left upper corner.
2nd cut: 4" down from Right upper corner to mid Left side.
etc.
However, if you start with a 16" square your finished result will be much smaller due to the seam allowances. Unless you add borders or sashing, which definitely give it a different look.
