Robert Lang - Finch

Issue 1, November–December, 2010

Diagrams: Finch by Robert J. Lang Edited by Jason Ku This complex design, from a square, uses a mix of 30 and 22.5 degree symmetries. This figure requires both soft 3-D rounding and precise skinny-flap folding. For best appearance, fold mostly dry from a surface-sized paper (see here for a description of surface-sizing), then selectively dampen the legs and portions of the body for shaping. For your first attempt, foil-backed paper (folded entirely dry) works well. .

16. We begin a complicated combination of swivel folds. Form two valley folds on existing creases and connect their tops with a new valley fold. The model will not lie flat.

17. Form the next valley fold on an existing crease, and connect its top with the top of the right valley fold you just made.

18. Squash-fold and flatten completely.

13—19

19. Petal-fold. All the raw edges should line up with each other.

22. Mountain-fold the edges behind to line up with folded edges.

20. Repeat on the left. 21. Fold the flaps out to the sides, folding all layers together.

23. Fold and unfold along angle bisectors.

24. Crease mountain folds along existing creases through all layers.

25. Bring the top corners toward each other while swinging one layer up in front and one behind. As you do this, try to avoid making a sharp horizontal crease between the two crease junctions.

28. Like this.

26. Like this.

29. Reverse-fold, folding as much paper as possible behind.

27. Petal-fold the hidden edge.

30. Fold the flap down, forming a squash fold at its base utilizing a vertical existing crease.

31. Fold the flap back up.

37. Bring the raw edges to the front.

38. Shift some paper toward the center.

39. Fold the edges out toward the sides.

40. Fold the tail up as far as possible.

42. Crimp the two legs down and slightly backward.

43. Mountain-fold the fold edge inside. Repeat behind.

44. Crimp the head upward, keeping the body round and 3D.

46. This is the view from the underside.

49. Fold the tip of the beak in half, adjusting the layers so that all of the folded edges are aligned.

45. Form a rabbit ear from about 1/3 of the tip of the flap. (There is no fixed reference point; by varying this step, you can vary the beak size to create different types of finch.)

47. Reverse-fold the tip.

48. Reverse-fold the tip upward.

50. Dent the top of the beak and pinch it. Crimp the head downward and round it. © Copyright 2006–2010 by Robert J.
