Origami heart

Step 1: get a square of paper. I used post it note size but you could make it as bit or as small as you like.

Step 2: fold in half diagonally and open back up

Step 3: fold in half diagonally from the other corners and open back up

Step 4: fold the top corner to the middle crease

Step 5: Fold the bottom corner to the middle of the top line 

Step 6: fold the right side so it touches the place where the bottom corner went to meet the middle top.

Step 7: repeat with the other side.

Step 8: fold the pointy corners on the left and right behind the heart.

Step 9: Fold the top pointy corners behind the heart.

Your origami heart is now complete :)
