When we pin the units together
we will be able to "lock" these
seams together and achieve the
desired perfect points as shown above.
We could only make this happen by
planning our pressing method beforehand.
We needed to press some seams to the light
fabric to make this happen.
Once again, after sewing the rows together
we will press the seam in row 1 to the left
and the seam in row 2 to the right so we
can "lock" them together.
