Works in Progress

This album groups models which have pictures taken at a Work in Progress [WIP] stage. They are usually not as nice as images of finished models, but they may offer insights related to the design and folding process. Note that there is a separate album for precreased sheets, which could be seen as very early stages of folding.

Parallelograms (prototype)

Parallelograms (prototype)

This is the prototype fold of Parallelograms Tessellation. It’s quite representative of my design technique: a quick doodle on a small grid and a rough sketc...

2021

This model took me longer than I expected, but better late than never, so: happy New Year 2021! This model uses a new tessellation molecule of mine which I h...

Monument Valley Corrugation

Monument Valley Corrugation

Her Majesty’s Box (WIP)

A new box, aptly named Her Majesty’s Box, taking shape on the train back from the 50th Anniversary Convention of British Origami Society. Both the convention...

Saturn Tessellation

Saturn Tessellation

This tessellation is based on a 128×92 grid. Image is created from a four-sink-base tessellation by folding up some of the squares’ corners. While I’ve seen ...

Crystal Structure of Gibbsite

Crystal Structure of Gibbsite

I designed this model as cover art for Surface Charging and Points of Zero Charge, a book by my father, Marek Kosmulski. It is a reference work in electro- a...

Menger Sponge (level 2)

Menger Sponge (level 2)

This is a labor-intensive, but very satisfying to fold model. Some people have managed to go as far as level 3 but even level 2 was quite challenging. About ...

Large Icosahedron

Large Icosahedron

This icosahedron has nine triangular pyramids pointing inwards on each face. The same shape can also be described as a truncated icosahedron whose each face ...
