Take two ear pieces, one with interfacing and one without, and place them right sides together. Sew the edge at 1/2 inch seam allowance with a sewing machine. Notch and trim the excess seam allowance. Flip right sides out and press flat. Then, press 1/2 inch of the top edge to the inside. Repeat with the other ear.
