The first template, 2½" x 6", contains the designs that are to be cut out and assembled. The second template, also 2½" x 6", contains size and shape approximations for those designs requiring a backing, except for number 4, which is a charm disc that could be cut out and number 3, an alternate French Hens design. The numbers on the designs in both templates refer to the day in the song and in the tutorials.
Hearts are often seen in combined with turtle doves in jewelry. When I realized that a left and right wing set side by side resembled a heart shape, Bingo! Heart shaped wings. A wider tail would also look nice so both cutting lines are shown on the template.
Decide on what texture or metal stamps to use for the bird wings. Because any texturing/stamping will distort the metal shape, it is best to texture the 24-gauge Argentium sheet metal before cutting out the design. Glue the templates in place on the metal. Cut the bird bodies and wings out.
