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:
Online 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 windtop 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:

true joy to fold and assemble. Will collapse flat
and pop back into shape. Modules / Paper
shape / Folding geometry: 2 modules from squares
using standard folding geometry.
Designer /
Date: Robert Neale, 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

Name: 2part 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.

Name: Cushions are
a series of 2part designs from squares and other
rectangles developed from Molly Kahn's
Preliminary Ornament and the Oblong Ornament. Modules / Paper
shape / Folding geometry: 2 modules from any
rectangle.
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. Modules / Paper
shape / Folding geometry: 2 modules folded from
double bronze rectangles using 60/30 degree
folding geometry.
Designer /
Date: David Mitchell, 1989.
Diagrams:

rectangle using standard folding geometry.
Designer /
