Step 1

Here's your origami sheet. (Notice "love" becomes "note" when flipped upside down? Crafty. But don't worry if all you have is a plain sheet of paper. Design it yourself!)
Step 2

Flip the origami over so that the inside of the note is facing up. Fold in half so the lower point touches the upper point.
Step 5

Fold the top flap (the one you just folded over) to the right at the halfway point.
Step 7

Slip your finger between the layers of the top flap. Pinch the point indicated by the circle and bring it up to the arrow, squashing as you go, to form a diamond.
Step 11
