You will need a piece of paper and your hands.
First you will take the corner of the paper and fold it to the right. You will unfold the paper and do the same to the opposite corner.
You will then fold the paper inwards along the crease and flatten it out.
You then get the right flap of what is now a triangle and fold it upwards and you do the same for the opposite side.
Now you fold the bottom rectangle upwards
You now have two sides sticking out. You will fold both of those in.
You flip the paper over and fold both bottom corners up.
Now you fold the top flap down and tuck the corners of the bottom flaps into the top flap.
You then get the two flaps that are leftover and fold them diagonally to form the heart and tuck those sides in as well and how you have a paper heart!
