Woven Octahedron

The woven octahedron is a bit of a challenge – also explaining how to.

  1. Cut out the 2 x 2 identical pieces, colour A (=yellow) and B (=purple)
  2. Score and crease along the imaginary lines between corners of the hexagon. The four small pyramids must all swirl in the same direction (#1)
  3. Fix the top pyramids with glue and only those (#2)
  4. Take two pyramids, one colour A one colour B
  5. Place the non-pyramid end of the flap in colour A into the small pyramid of colour B
  6. Turn until the start of the longest strip in colour A is parallel to the flap in colour B (#3)
  7. Weave the start of the longest strip in colour A into the three strips in colour B coming out of the flap in colour B. The pyramid shall remain in colour B
  8. Line up and fix with glue along the woven strip (#4)
  9. Weave the rest of the face, line up and fix with glue. Both small pyramids shall be colour B now (#5) – and from the inside (#6)
  10. Now bring in the other piece in colour B
  11. Insert the non-pyramid end of the flap into the small pyramid of colour A. On the inside the flaps shall run along opposite edges, flaps following faces next to each other (#7)
  12. Weave the beginning of the longest strip in colour B into the colour A strips coming out of the woven face (#8)
  13. Line up and fix with glue
  14. Weave the rest of the face, line up and fix with glue. Notice that the faces of the small pyramids are colour A here (#9)
  15. Take a look at the inside of the octahedron. Identify the small pyramid only having one flap inserted. The colour of the pyramid should be B
  16. Bring in the last piece in colour A
  17. Insert the non-pyramid end of the flap into the identified small pyramid of colour B. On the inside the flaps shall run along opposite edges, flaps following faces next to each other
  18. Weave the beginning of the longest strip in colour A into the colour B strips coming out of the woven face
  19. Line up and fix with glue (#10)
  20. Weave the rest of the face, line up and fix with glue. Notice that the faces of the small pyramids are colour B here (#11)
  21. Now you shall finish the last face in the upper half of the octahedron. Fix the longest trip in colour A to the flap and small pyramid in colour B coming out of the very first face you made (#12)
  22. Identify the col0ur B strips required for this face and weave in the longest
  23. Line up and fix with glue (#13)
  24. Weave the rest of the face, line up and fix (#14)
  25. Identify the unwoven face with two sets of strips coming up from the woven half part of the octahedron
  26. Weave using the strips of colour A. Here a pair of tweezers is a help
  27. The next face to weave is the face with the short strips in colour A. Start weaving the longest strip in colour B, line up and fix
  28. Weave the rest of the face, line up and fix
  29. Then weave and fix the face with the short strips in colour B
  30. And finally weave in the short strips of colour A into the last face. Tweezers required. Line up. By now fixing is not required.

  1. Trudne zadanie, ale to jak w życiu. Im trudniej tym bardziej chce się pokonać niemożliwe. Gratuluję twórcom i odtwórcom. Joanna
