Step 2: Free form
The heart is free form and cut from a piece of an old food box that was destined for the bin!
You will need 2 heart shapes, one slightly larger than the other.
Since these will have to nest together make sure that the larger one is big enough to make room for the cardboard core and tape layers.
Cut the original heart from cardboard then flip it over and trace the edge on another piece.
Cut the larger one about 2mm outside of the edge of the smaller one.
