Arrange the 9 squares into a traditional 9-Patch quilt
block (a 3 x 3 square
block with alternating colors). Place the light colored squares in
the four corners and in the middle square and the dark colored squares
as the remaining four squares. The entire 9-Patch quilt block should
be 150 x 150 pixels.
(Using the reverse 9-Patch quilt square with 5 dark colored
squares and four light colored squares is also possible and
will give a deeper feel and color quality to the quilt).
