Next place a Color 1 1-1/2" square right
sides together against the lower left edge of a Color 2
4-1/2" square with outside edges aligned. Draw in the
diagonal and sew on the drawn line. Cut off the excess seam
allowance and press the remainder towards the corner. Repeat with
another square on the lower right corner. Make four units like
this...
Then lay out all the units as shown at left. Sew
three horizontal rows. Join the rows and the block is complete!
Here are four blocks by five in various Asian
fabrics :o)
