    This models design borrows from Robert Langs dragonfly in The Complete Book of Origami (Dover, 1988). For your firstattempt, begin with a 3x7 rectangle considerably larger than a dollar bill. A dollar bill makes a model 45mm long with a 63mmwingspan, and requires tweezers.

    1. Begin green side up.Valley-crease the long way,mountain-crease the shortway.

    2. Bisect the middle 4right angles with valley-creases.

    3. Rabbit-ear. Repeat on left.

    4. Fold and unfold. Turnover and rotate 1/4 turn.

    1/4

    5. Crease bisectors,stopping where shown.Then swing flaps around.

    6. Crease bisectors.

    7. Collapse. A layer swingsout from behind at the 4 tinyarrows, and the long flapsstand straight up.

    8. Swing the left half of the centraldiamond under the right half; thestanding flaps fall to the left. Nonew creases. Rotate.

    9. Reverse-fold onexisting creases.
