Out of main block fabric, cut 4 squares 2 3/4" x 2 3/4".
Iron the freezer paper block template to the right side of the main fabric nine patch, lining up the seam lines.
Cut out the shapes, leaving a seam allowance for turning under.
Baste through all layers to secure them. Do not baste so close to the freezer paper edge that you won't be able to turn under the seam allowances.
Clip all the inside corners.
Trim away the excess background fabric from the back of the block.
