Disappearing hourglass block

First you start with 2 squares, any size (I cut mine 8"), sew around all 4 edges, cut on the diagonals and put together as hourglass.

then you cut into thirds on all 4 sides and put together as shown

here are 4 squares with the dark corners together

and again with the light corners together

Is it not awesome?  I love it!  I think I will make a baby size quilt to begin with...
