  Name: The Preliminary Ornament is made by the simple expedient of weaving together two Preliminary Folds.

Modules / Paper shape / Folding geometry: 2 modules from squares using standard folding geometry.

Designer / Date: The earliest publication of this design that I know of is in The Origamian Vol 7 Issue 4 of Winter 1967 where it is called Tree Ornament and attributed to Molly Kahn.

Diagrams: On-line diagrams are available in the Cushions pdf on the Modular Designs page of this site.

 
  Name: The Spinner, originally a hanging ornament but also makes an excellent wind-top if held between the palms and blown at gently.

Modules / Paper shape / Folding geometry: 2 modules from squares using standard folding geometry.

Designer / Date: Attributed to Alice Gray in Paul Jackson's 'Origami Christmas Tree Decorations', British Origami Society booklet 20 published in 1982, although it is clearly a simple variation of Molly Kahn's Preliminary Ornament. I do not know who first discovered it would function as a spinning toy.

Diagrams: Presented as an ornament - in Paul Jackson's Origami Christmas Tree Decorations - British Origami Society booklet 20 - 1982. Presented as an action toy - in Origami - David Mitchell - Barnes and Noble 2002 - ISBN 0-7607-3331-7.

Diagrams: As Octohedron In The Origamian Vol 8 Issue 3 of Winter 1968.

 
  Name: The Embroidered Ball aka the Skillman Ball has the interesting property that it can be squashed flat in two directions, although this property does not appear to have been known or appreciated at the time of its first publication.

Modules / Paper shape / Folding geometry: 2 modules from squares using standard folding geometry.

Designer / Date: Jack J Skillman, c1969..

Diagrams: In Flapping Bird magazine no 4, 1969. Also in More Origami: The Art of Paperfolding No 2 in 1971 and Origami Christmas Tree Decorations, Paul Jackson, BOS booklet 20, 1982.

 
  Name: 2-part Decoration

Modules / Paper shape / Folding geometry: 2 modules from squares using standard folding geometry.

Designer / Date: David Mitchell, 1989. Has also been independently discovered by Tung Ken Lam who realised it will squash flat in two directions, thus turning a rather ordinary paperfold into a charming toy. On seeing this I realised that the Skillman Ball will also squash flat, something I had previously not been aware of.

Diagrams: Not yet available.

 
  Name: Nordquist's Ornament

Designer / Date: In 2004, soon after seeing Paulo Mulatinho's UFO, I realised the same idea could be applied to larger grids and other rectangles. In 2005 Tung Ken Lam realised that the divisions of the grids need not be uniform.

  Name: The Modular Flip Flop is my reconstruction of a design by the Danish paperfolder Thoki Yenn which has become lost (probably because Thoki abandoned it in favour of his one piece version of the same design). The design is a version of a well known mathematical toy with the strange property that it will squash flat in two different directions.
