Print or trace the block pattern onto foundation paper, number, and cut out as in the photo.
Note that we didn't piece the small triangles at the bottom of the block.
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.
Trim to size, remove the freezer paper, and cut away the excess fabric from the back of the block.
