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.

Sew the triangles together in pairs.

Sew the two resulting pieced triangles together.
(Press all seams open.)

Print or trace the block diagram onto the dull side of freezer paper and cut out as in the photo.
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.

Applique. Because you pressed the seams open you should be able to undo the corner seams just a little and they will fold back to the wrong side easily.

Remove the freezer paper and press.

Mark the positions of the melons on the block and, using your favorite applique method, applique them in place on the block.
I used "freezer paper inside".
Trim the block to 5" x 5".
