Download and print Heart template. Cut out 2 squares of parchment and 1 of tissue paper, all slightly larger than template. Sandwich tissue square between parchment ones; pin to prevent slipping. Trace heart onto top sheet with a pencil.
Using contrasting thread, machine-stitch 3/8 inch inside heart outline, leaving a 3-inch gap.
Trim excess paper, leaving a 3/8-inch border around stitching. Slide candies and note under top parchment layer. Machine-stitch gap closed.
