Finally! I have a block made. I'm never going to make my goal if I don't speed up this progress.
Cut a 6" x 6" square out of background fabric and cut it in half on the diagonal twice.
(Press all seams open.)
Iron the freezer paper template to the right side of the background fabric block section, centering it carefully and matching up the seam lines.
Cut out the center shape leaving a seam allowance.
Out of main block fabric, cut a 4" x 4" square. Lay the square right side up on the table and place the background fabric section right side up on top of it, centering it carefully.
Baste through all layers, far enough from the freezer paper edge to allow for the seam allowance to be turned under.
I used "freezer paper inside".
Trim the block to 5" x 5".
