$ Heart-and-Arrow

A dollar bill makes a model 30 mm x 45mm. For your first attempt, begin with a 3x7

rectangle larger than a dollar bill.

1. Either side up. Crease at

eights horizontally, halfway

vertically. Flex all creases both

ways.

2. Make this crease sharp

only where it crosses the

center horizontal line.

3. Use the mark to make

crease “A”. Then use “A” and

the center vertical line to make

crease “B”, at the same

distance. Flex both.

4. Horizontal creases not

shown. Bisect the rectangles.

5. Bisect the outer rectangles.

6. On each side, use the outer

2 creases to add another.

line

7. All creases shown.

Mountain the top and bottom

eighths behind.

8. Swing behind on the

indicated crease. Turn over.

9. Flip down the top eighth,

squashing the corner at the

right.

10. Pull out paper from under

the squash, flipping down the

long edge.

11. Swing over the long

flap, while pulling up the

triangle shown.

12. Swing flap back on

existing crease, while flipping

down the top eighth and

squashing a tiny diagonal.

13. Swing back. Both sides

of model will then look similar.

14. Crease.

15. Pleat and sink on

existing creases.

16. Undo last step. Turn

over and repeat 14-16.

17. Crease top flap.

Repeat behind.

18 . Reverse-fold on

existing crease. Turn over.

19. Reverse-fold on the

crease; rear-half is double

thickness.

20. Swing flap to left on

existing crease, squashing

only the tiny diagonal

indicated. The X-ray line is

a hidden valley fold.

21. Segment “C” is the new

crease. Swing back down on

existing crease, squashing the

diagonal shown. The X-ray line

is a hidden valley fold.

22. Fold the new flap to

the right.

23. Reverse-fold at the top,

closed-sink at the bottom.

24. Pull gently open at the

top, and reform the sink

from step 15 .

20-24

25. Repeat 20-24 behind.

26. Reverse-fold. At the left

end, only the embedded layer

is reverse-folded.

27. Swing flap to the left,

squashing the corner behind it.

$ Heart-and-Arrow (cont.)

28. Swivel again. Note the

tiny squash (mountain-fold).

29. Flip up an edge, opening

the triangular pocket.

30 . Closed-sink the small two-

toned trapezoid. Then swing

the pleated flap to the right.

26-31

31. Swing down 2 edges,

swiveling under the sunken

area. Repeat 26-31 behind.

32. Swing the large, hidden

triangular flap upwards,

reverse-folding the left side.

33. Reverse-fold the

middle triangle upwards.

tail

34. Valley-fold it back down,

into the pocket immediately

in front of it (a tight fit, even

if accurate). Turn over.

35. Reverse-fold the top

point down, tucking the tip

into the pocket immediately

in front of it.

36. Like so. Now we begin

on the tail of the arrow.

37. Tail: notice pleats

are not perfectly

symmetric. Reverse-

fold.

38. (Not all edges shown.)

Swing over.

39. Rotate.

37-40

40. Bring one layer to

surface (a closed-sink).

41. Thus. Turn model over

top-to-bottom.

42. Repeat 37-40, treating the

double-thickness as one layer.

Turn back over (top-to-bottom).

43. Tuck in the loose triangle.

44. Reverse-fold protruding

edges as if they were a single

edge.

45. Pull out paper and swivel

down the front edge. The X-

ray line is a horizontal valley-

fold that becomes a vertical

mountain-fold flush with the

right edge of the model.

46. Swing the middle triangle

down and behind, dragging

the upper triangle.

47. Tuck the loose triangle into the second

pocket (between pleats, not into the sink).

Tail complete. Turn over side-to-side.
