$ Shamrock

A dollar bill makes a model 70mm wide and 50mm tall. For first attempt, you may wish to

use a larger 3x7 rectangle.

pivot

1. Start green side up.

Valley-fold in half.

2. Pivot at lower-left corner,

valley-fold lower right corner

to top edge.

3. Repeat step 2 behind.

Unfold completely and

turn over.

4. Valley-fold on existing

crease.

5. Bisect angle.

Crease only halfway

up, then unfold.

6. Valley-fold raw edge

to folded edge.

4-7

7. Pleat, bringing existing

mountain-crease to folded

edge. Unfold completely.

8. Repeat 4-7 in mirror

image.

9. Valley-fold halfway and

unfold.

$ Shamrock (continued)

10. Pleat on existing

creases. Order of layers

is not crucial. Turn over.

11. Mountain-fold on the

existing crease, creasing

sharply. Unfold completely

and turn over.

12. Add valley-creases.

The middle one and outside

pair are on existing crease

lines. Squeeze in the other

two last. Turn over.

13. Triple-crimp. Start in the

middle, work outwards. The new

valley-folds fall where natural;

they don’t bisect angles. The

model will lie flat along the

existing radial creases.

14. Enlarged. Reverse-

fold. Valley-line exists.

Repeat behind.

15. Valley-fold to half-way

crease and unfold. Flex the

upper crease backwards.

Repeat behind.

16. Closed sink the upper

corner. Mountain-fold the

lower. Repeat behind.

17. Closed-sink the next

corner, along the same line

as the previous sink. Repeat

behind.

18. Swing down. Note

new crease at the right.

$ Shamrock (continued)

18-19

19. Valley-fold edge “E” a little

bit above the crease line. A

flap comes out at bottom.

20. Like so. Repeat 18-19

behind.

21. Difficult step: fold edge

“F”down to leave a tiny gap

between “leaves”. Do the same

on the back version of “F”. Also

spread lower flaps outwards.

1:push down

22. View of back side. The small triangle is

a 3-sided open-faced pyramid. Push down

inside it to resolve tension on front side. Then

pinch it from the sides, and swing it down to

either side. Turn over, top-to-bottom.

23. Flatten completely and sharpen

creases. From this point on, results may

vary a bit due to judgement folds. Try to

keep left and right sides reasonably

similar.

24. Mountain-fold through all

layers, sharply only on the

rearmost ply. Goes through the

bend in the middle “leaf”, at right

angles to crease “D”. Turn over,

top-to-bottom.

25. An asymetric petal-fold.

Fold in the order shown.

Folds “1” exist. “Roll in” folds

2 and 5 with a fingertip.

26. Squash the standing

flap. Start with the folds

joining points “A” and “B” to

the “petal-peak”. See next

diagram.

$ Shamrock (continued)

24-26

27. Approximate

positioning shown. Repeat

24-26 on left side. Make

minor adjustments to keep

model symetric.

28. Repeat 24-26 (the

asymetric petal-fold).

29. Like so. Repeat last step

on the left side. Left and right

side will probably diverge more;

try to keep them similar. If any

paper shows between leaves,

swivel it upwards.

30. Tuck as much as possible

inside (behind the petal folds),

pleating if necessary.

31. Reverse-fold, closed-

sinking at the thick corner.

Judgement fold: check

front side.

32. Squash-fold. Hidden

valley-fold makes top of leaf

symetric.

30-33

33. Stuff the flap into

the pocket behind it,

pleating if necessary.

34. Repeat 30-33 on

left side.

35. Thin the stem on both

sides. The crease bends,

then becomes a spread-

squash.

$ Shamrock (continued)

36. Entire model not shown.

Valley-fold stem into position.

Turn over top-to-bottom.

37. Middle leaf. Reverse-

fold, distributing layers

evenly. Repeat on left side

of leaf.

38. Shape tip of leaf with a

“divot”. Repeat on left and

right leaves.

39. Trim with reverse-folds,

as needed.

40. Finished Shamrock.
