No, it was easy. Here's a link to the way my blocks were made:

They are really just 3.5" squares with the top right and lower left corner having a 2" square sewed over it, snipped & flipped. Make 9 of those units and sew together just line a traditional 9 patch. Kind of mindless if you've got all your pieces cut and laying by the sewing machine.
