Add a B unit to the right of the unit we just made. Press the
seam towards the newly added B unit...
Add the other A unit to the bottom, again pressing the seam towards
the new addition...
Now add the last B unit. sewing from the bottom to a point 1/4"
from the top edge of the B unit. Backstitch one stitch to secure that
end. Remove this from the machine now and line up the remaining
un-sewn partial seam. Stitch from the inner 1/4" point to the
outer edge of the block...and you are done!
Here are four blocks by five with alternate blocks
rotated 1/4 turn to the right! There are MANY different ways to Color
this one though, as shown on the next page...
