Fold to meet the center line, and fold another side to the center line.

Do the same for the yellow origami.

Vally-fold the left top corner of the purple origami to meet the purple’s right edge.

Vally-fold the right bottom corner of the purple origami to meet the  left edge.

* Be careful! You have to do the opposite for the yellow origami*
Vally-fold the right top corner of the yellow origami to meet the yellow left edge.
Vally-fold the left bottom corner of the yellow origami to meet the  right edge.

Fold the both origami in half  as shown below right.

Unfold.  Hold the purple origami’s top and twist it to the left so that  right edge meets the center line of the purple origami.

You should see a triangle on the top half, like shown below.
Hold the purple origami’s bottom & twist it to the right so that  left edge meets the center line of the purple origami.

Now, hold the yellow origami’s top and twist it to the right so that  left edge meets the center line of the yellow origami. Hold the yellow origami’s bottom & twist it to the left so that right edge meets the center line of the yellow origami.
