Easy.

Print or trace the block pattern onto foundation paper, number, and cut out as in the photo.

Foundation piece the numbered sections. Trim the seam allowances to 1/4".
Note that we didn't piece the small triangles at the bottom of the block.

Sew together the two center sections of the block.

Attach the remaining two sections.

Print or trace the bottom block section onto the dull side of freezer paper and cut out as below.
Iron the freezer paper into position on the right side of the block, lining up the seam lines. Cut out the small triangles, leaving a small seam allowance. Clip the inside corners.
Out of main block fabric, cut a rectangle about 6" x 4" and lay it right side up on the table.
Place the block right side up on top of it.
Baste through all layers. Do not baste too close the the edges of the triangles because you want to be able to turn under the seam allowance in the next step.

Turning under the seam allowance, reverse applique the small triangles.
Trim to size, remove the freezer paper, and cut away the excess fabric from the back of the block.
Press.
