$ “One-Way” Arrow

A dollar bill makes a model 100mm long and 32mm wide.

Rectangles of other dimensions may also used, provided they are “considerably” longer than they are wide.

1/4

1. Start with the “ONE” side

up. Crease at eights, but not

sharply on the middle crease.

Turn over and rotate 1/4 either

way (depending on which way

you want the arrow to point).

2. Starting the “point” of the

arrow. Valley-fold.

3. Fold and unfold through

all layers. Repeat on right.

4. Pleat. Make the

valley-fold first. Then

bring the mountain-

fold to the indicated

intersections.

5. Reverse-fold

corners at 45 degrees.

Easiest to bring long

edges to center,

squashing the corners,

then close up.

6. Reverse-fold the

long edges, closed-

sinking at the top

corners. Start at

the open end and

work up.

7. Valley-fold all

layers on existing

crease.

1/2

8. Reverse-fold other

corner on existing

creases, tucking into

triangle on left. The

tiny valley-fold at the

right edge helps make

the tuck easier.

9. “Point” finished.

Rotate to other end

and turn over.

10. Begin working

on the “flights”.

Reverse-fold top

layers.

11. Sink inside.

12. Swing out the raw

edges from behind.

Model is not flat at the

“point” end.

13. Reverse-fold.

Repeat on left.

14. Swing down.

15. Wrap a single ply

around the central

trapezoid. Easier if

you open the model

up considerably.

16. Pleat. First mountain-fold

along bottom of trapezoid.

Then valley-fold to line up with

indicated edge. Unfold pleat

and turn over.

17. Swing side strips in to

middle. Model not flat at

top; concave “ear” shapes

form.

18. Valley-fold top layer,

between pleat lines, which lifts

the “flights” perpendicular.

19. Continue flipping over

the “flights”, squashing a

new trapezoid beneath the

one you wrapped earlier.

20. Like so. Model is

now flat. Turn over.

21. Tuck the new upper

trapezoid inside the one

behind it, which was wrapped

earlier.

22. Flip the tail assembly down.

23. Pleat and tuck under diagonal edges.

Gently bend the model along the vertical with

a mountain-fold to facilitate the tuck. Then

flatten out to secure.

24. Finished.
