It's hard to tell from the pictures, does it have a flat side or is it a two part mould that makes a 'full' heart?

The heart would have a flat side, what you could do is make two flat sided hearts and join them together.
If you did do this we recommend using a lot of sugar to make the jelly more dense (and less wobbly!).
