Beadwork, Polyhedra

Rhombicosidodecahedron

Rhombi-what? Like a dodecahedron, but with some extra squares and triangles between the pentagons! My beaded version looks like this:

Technically it’s a small rhombicosidodecahedron, since there’s also a great rhombicosidodecahedron, which has hexgaons instead of triangles and decagons (I think that’s the right word for a ten-sided polygon) instead of pentagons.

It’s actually based on my previous icosahedron model, although it ended up being a slightly different shape in the end. It took me a while to work out which polyhedra it corresponded to, but a rhombicosidodecahedron is an expanded icosahedron so that makes sense! Here’s photo of the two together:

Another thing it turned out to be is really difficult to photograph! Not helped either by the lack of sunshine today (why is it always cloudy every time I finish a piece?).

It’s made using 30 individual diamond-shaped pieces. These are made using some CGB techniques – each one is made up of two layers built from an MRAW band, with two side increases on the bottom side and four on the top. It was definitely a bit of a marathon making 30 MRAW bands though!

Hopefully the weather will improve and I’ll be able to get some better photos soon!

  1. Dear Patricia,
    Will there be a tutorial for this rhombicosidodecahedron?
    I could figure out how to make the single component, but the way
    to connect them is hard. Is it the same way as the icosahedron?
    If so, I will go to easy to buy the pattern.

    Take care

    1. This is actually next on my list to write a tutorial for! (But at my usual rate of progress it might take me a while 🙂 ) It is connected in a similar way to the icosahedron though so that should work!
