Origami Secret Heart

Origami Secret Heart is an interesting design by Florence Temko. On the outside you see a heart and when you opened the heart slightly, it opens to reveal a box inside. It's called secret heart but maybe it can also be called origami secret heart box?

Origami Secret Heart Step 1: Start with a 6 inch x 6 inch (15cm x 15cm) square origami paper, color side down.

Fold paper in half on both diagonal axis. Crease well and unfold.

Origami Secret Heart Step 2: Fold all 4 corners to the center. Crease well and unfold.

Origami Secret Heart Step 3: Flip paper over. Fold the top left corner to the meet the crease line. Also fold the bottom right corner to meet the crease line.

Crease well.

Origami Secret Heart Step 4: Fold the top left and bottom right over the existing crease lines.

Origami Secret Heart Step 5: Now at this point, you could write a message in the area shown below. Later when you "open" the heart, you'll see the message inside the box.

Fold both the top left and bottom right to meet in the center.

Origami Secret Heart Step 6: Rotate paper so that it's horizontal.

Origami Secret Heart Step 7: Fold point A to C. Crease well and unfold.

Then fold point D to B. Crease well and unfold.

Origami Secret Heart Step 8: Make 2 diagonal folds as shown below.

Origami Secret Heart Step 9: Now fold the right tip over to the left. Press paper flat.

Origami Secret Heart Step 10: Fold the top and bottom tips to the center. Crease well.

Origami Secret Heart Step 11: Fold the other tip over to the right.

Origami Secret Heart Step 12: Now make a vertical fold, bringing the top layer over to the right edge.

Origami Secret Heart Step 13: Rotate paper 180 degrees. Repeat Steps 8 to 12.

When completed, your paper should look like this.

Origami Secret Heart Step 14: Just a few final folds to form the shape of the heart.

(If you've written a message inside, you may want to peek inside to check the orientation before you shape the heart. You do not want your message to be upside down! Thanks to Tomodachi for his comment.)

First make 2 diagonal mountain folds as shown. You can check our page on valley and mountain folds if you're not familiar with them.

All the folds we make are generally valley folds. Mountain folds are the exact opposite of valley folds.

Origami Secret Heart Step 15: Now make 2 smaller diagonal mountain folds, one on the top right and one on the top left corner.

Origami Secret Heart Step 16: Finally make 2 even smaller diagonal mountain folds on the top inner corners.

and your origami secret heart is complete!

Pull the heart open and there's a box inside!

If you've written a message on Step 5, then you'll see it inside like this:
