Using a pencil and ruler, draw a diagonal line from corner to corner
on the wrong side of all cream 3-7/8" squares.
With right sides together, layer a cream 3-7/8" square on a
brown 3-7/8" square. Stitch a 1/4" seam on each side of the diagonal line
that you drew in Step 1. Cut apart on the drawn line and press seam
allowance toward the darker fabric. Trim points. Repeat five times
more for a total of ten cream/brown half-square triangles.
Arrange cream/brown half-square triangles and the cream 3-1/2" squares as shown
in Diagram 1. With right sides together and using a scant 1/4" seam, sew together to form rows as shown in Diagram 2. Sew rows together as shown in Diagram 3 to finish the block.
