Out of main block fabric, cut 4 squares 2.5" x 2.5"
Iron the freezer paper shape onto the right side of the nine-patch, lining up the seam lines.
Cut out, leaving a scant 1/4" seam allowance.
Baste the main fabric shape onto the center of the background fabric square. (I forgot to take the photo until I had started the applique.)
Trim the block to 5" x 5" and press.
