Think of the 16 patches as the blocks, the flying geese as the sashing with white cornerstones.
Or you could construct it as 2 different alternating blocks. The "A" block (outlined in green) has the flying geese pointing away from the 16 patch. The "B" block (red) has the flying geese pointing in. You will then need to add a border on the left side & bottom to complete the pattern.
Then just pick a number for the 16 patch: Like make the squares finish at 1" (cut them at 1.5"), then the flying geese need to finish at 2X4", and the white square finishes at 2"
