Simple but effective!
For this one print:-
The New Orleans Jazz motifs onto quality white card
Cut out one of the large motifs and a length of the border to fit the front of a white 7" x 5" card blank. Stick the border into place with double-sided tape.
Stick the motif onto a larger piece of silver metallic card with double-sided tape and trim round with a craft knife and ruler to leave a small border.
Fix the motif piece into place with sticky pads. Add a greeting to the border strip if required.
