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.
Because any texturing will distort the metal design, it is best to texture the 24 gauge Argentium sheet metal before cutting out the design. Any texture will work, simple or fancy, so long as you like it. Textured sheet metal is available and is a great alternative to doing the texturing yourself. Anneal and flatten metal you texture before continuing.
