Fold in half, unfold, fold the other half, unfold, fold top and bottom edges to the center line, fold bottom corners to top center and unfold, fold top corners to bottom center and unfold, fold outside edges where the diagonal lines cross and unfold, fold the four corners to the lines just made, and this is where the procedure becomes a tad involved... Now there you have it: an origami heart, splendidly suited for folding love letters.
For lovingly unfolding emails, try this popping IncrediMail letter:
›› Send an email that overflows with hearts, and notes, and love. (IncrediMail)
