What do you use to draw the shapes of the faces prior to cutting out?
Certainly the colours do look good - I've always felt that the card that I use looks a bit drab!

I'm about 40% of the way through a stellation of the "degenerate" with the great dodecahedron edge inscribed in its icosahedron shell. I'm using 16 colours - 6 easily distinguished colours for the dodecahedral faces and 10 far less identifiable colours for the icosahedral. I selected the colours in ...

I bought twenty nine different colours of card, so I have enough choice for most models. Like you I'm red-green colour blind, so I have to write on each sheet of card what colour it is. I can handle 5 colours for hexecontahedra and 4 colours for icositetrahedra, but for triacontahedra I normally use...

I must admit I'd be tempted to use ten colours for the triangles and six colours for the decagrams and pentagons. Keep us posted on progress and post a picture or two when you've completed it. I've currently got my eye on a stellation of the icosahedron with chiral tetrahedral symmetry that appears ...

...join two cubes and "hyper-fold" along the joined face to rotate one cube into the fourth dimension. Back in the mid 60s I, as a third former, walked proudly into the sixth form mathematics room with the hypercube that I'd made from acetate sheet only to have it dismissed by a sixth former who to...

My brain is obviously too ingrained with 3D! I can understand (for example) all the stages of a draw-polytope from zero through to three dimensions, but I cannot visualise how to effect the stage beyond three. You have your X, Y and Z axes. How do you go beyond these? You can convert a tessellation ...

You can view a polygon (two dimensions) as a line (one dimension) by looking at it edge on. But you cannot view it as a point (zero dimensions). You can view or draw a two dimensional image of a polyhedron (three dimensions) But you cannot view or draw it as a line (one dimension). I wonder, therefo...

Thanks for your help. My glue isn't that good for model making, its stringy and takes around ten minutes to set. Try using Balsa Cement. It dries very quickly. What sort of paper or card are you using? Cartridge paper works OK, but I'm happier using 160 gsm card. I never use single tabbing now. Dou...

Three pictures of a sort of Isohedron where the 5th vertex of the pentagon is on the opposing edge. It's a stellation of the regular dodecahedron. http://i112.photobucket.com/albums/n174/oxenholme/StellatedDodecahedron1.jpg http://i112.photobucket.com/albums/n174/oxenholme/StellatedDodecahedron2.jpg...

http://i112.photobucket.com/albums/n174/oxenholme/twocubicisohedra.jpg It is interesting (at least I think it's interesting!!!!) to compare the stellation of the pentagonal icositetrahedron on the left with the isohedron on the right. The one on the left is a sort of special case of the one on the ...

Do you ever make polyhedra for other people?
Nicola at work had never previously encountered polyhedra. I doodled a line drawing of the small stellated dodecahedron and she was fascinated, quickly asking me to make a model for her. I find it a tad tricky to get the small stellated dodecahedron perfect, so for the time being I made a great dode...

Octahedron plus Dodecahedron
I spotted this among the compounds in Stella and had to make it. I tried using a multicolour octahedron and a plain grey dodecahedron. It looks super in the flesh and a bit ordinary in the pictures. I have yet to get a printer, so I had to work out the net for myself... http://i112.photobucket.com/a...
