1) First off, one of my old favourites: a dodecahedral kusudama flower ball

You could make a daffodil-yellow version for Easter...

3) A fabulous fractal make: @standupmaths and @thinkmaths’ Sierpinski tetrahedrons. Go as big as you dare!

Or try your hand at a Menger Sponge or Koch Snowflake: https://www.think-maths.co.uk/downloads/building-3d-fractals

4) Been stockpiling? Use up those empty toilet rolls to make this fantastic truncated icosahedron with the instructions from @mrallanmaths’ 8000th tweet

5) How high can you go? Make a Columbus Cube tower with David Mitchell’s instructions: http://www.origamiheaven.com/pdfs/columbus.pdf

If you have time, explore his whole website – a treasure trove of mathematical #origami! http://www.origamiheaven.com/

6) Or how about a tower of skeletal octahedra instead? They’re a great challenge to put together – although you might need an extra pair of hands!

Good video instructions from @nrichmaths here: https://wild.maths.org/skeletal-octahedron

7) Paper not your thing? Pencils are? You’ll need a lot of them for the fantastically rewarding Hexastix!

See my #ArtfulMaths blog post here with excellent video instructions from @standupmaths: https://www.artfulmaths.com/blog/hexastix

PS elastic bands disintegrate so best use string instead

8) Back to some #origami! This paper version of a popular six-piece burr puzzle is a lovely fold, and would make a great gift.

Thank you to @DrOlsen314 for his blog post here: http://b3d.drjimo.net/3d-solids/burr-puzzle-origami/

9) Explore the tessellating properties of A-sized paper and create some tetrahedron wall art.

For instructions see my #ArtfulMaths blog post here: https://www.artfulmaths.com/blog/tetrahedron-wall-art

10) Light up your life with beautiful #origami cube lampshades!

Use baking or tracing paper with LED bulbs or fairy lights.

10a) These instructions from @origamifolding make the Sonobe lampshade below https://origamitutorials.com/sonobe-cube-lamp-tutorial/ Can you spot the Pythagoras’ Theorem proof?

10b) Experienced origamists might wish to try the challenging, but oh-so-stunning, Shuzo Fujimoto Hydrangea cube lamp.

I used @happyfolding’s video instructions for the modules & this video for the construction

11) Try some kinetic modular #origami and make Yami Yamauchi’s wonderful rotating Fireworks model

Again, @happyfolding has some useful video instructions:

12) Or get your tool box out and make some string art. You’ll need a hammer, nails or tacks, and some string. I used a canvas, but any board will do

Follow the steps in my photos below, or create some designs or your own...
