I'm going to try to show you how I made it, if it's not clear - SHOUT!
You will need:
Cardstock 11" x 5.l/2"
Nestabilitie Heart Die
Cuttlebug folder - Fantasy Flowers
Patterned papers, wire, beads
Fold cardstock and crease centre fold. On the card front - measure in from the centre fold 2.3/4" Top and Bottom and draw a pencil line.
Centre the heart die to this line and tape in position
To cut the shape I found that it was best to only sandwich the part to be cut inside the plates. Feed the flap through first, this will stop the plates banging down and marking the card.
Your card will be like this. You can now score down the pencil mark to the exact centre point on the heart so it will fold back.
I decorated my valentine card with a smaller heart die, embossed with the same folder, and then added wire and beads.
The pop up was made from cutting three hearts and fixing them together - to show you how versatile this pop-up is I have made a butterfly shape
