Icosahedron Constructions
These icosahedron/dodecahedron constructions are good practice for using compasses, finding perpendicular bisectors etc. Really good instructions here. https://www.youtube.com/watch?v=MKuyuZTw8EY
Columbus Cubes
Columbus Cubes are one of my favourite. Quite satisfying to make and stack. I keep meaning to do more with them. I found these in a book by David Mitchell (his website is well worth a visit!) His page about the Columbus cubes is here . There is also a video on YouTube on how to make them https://www.youtube.com/watch?v=6u-1a1UFj_k . There's even a kusudama to make with them. That's on the list to do in the future . It has now been done .
