I’m really pleased to say that I’m going to be an Ambassador for this year’s International Beading Week! I’m already planning beading activities and putting together some patterns and tutorials to share with everyone to celebrate the week!

This year International Beading Week (IBW) takes place from the 25th July to 2nd August. The aim is to bring beaders together and inspire people to take up the craft! More details of everything that will be happening can be found on the IBW website.

As a start I’ve been doing a bit of work creating pdf versions of the free tutorials here on my website! Hopefully this will make them easier to save and print. Here are the first two!

Spherical Harmonics

Spherical Harmonics is the Rick Rack Dodecahedron – which finally has a name! Spherical harmonics are a type of function defined on the surface of a sphere which have many uses in maths and physics. The visualisations of these functions remind me of the shape of the rick rack dodecahedron.

Trefoil Knot Kaleidocycle

Did you know that the trefoil knot kaleidocycle is also a Mรถbius kaleidocycle? If you use a different colour for one edge of the band of tetrahedra you’ll see that it has a twist when you join the ends together to make the trefoil knot!

The pdf versions of the folding cube and gyroelongated square bipyramid kaleidocycle tutorials will also be available soon!

# Rhombic Dodecahedron

Here’s a fun shape – a rhombic dodecahedron made from warped hexagons and octagons. I wasn’t sure how well this was going to work, but I really like the way each face looks like a slightly folded square. A rhombic dodecahedron has twelve diamond-shaped faces, so I knew it wouldn’t look completely symmetric and it’s interesting to see how it’s turned out!

I also really like the colour of these green delicas – I don’t use green very often but glad I did this time! I was also very relieved that inclusion of a few matte delicas (the row of brown beads) did not result in disaster! I’m always a bit wary of matte beads since they seem to break very easily, but treated with a lot of care they worked out well.

I started this about 2 years ago just before a move but it got left forgotten afterwards for most of that time. Decided it was about time to finish it last summer! It’s quite similar to the Hypernova dodecahedron in some ways – both are what I’m going to call vertex-hyparhedra, because they are based on the idea of placing higher-order hypars over the vertices of a polyhedron. I think I’m going to start calling the other beadwork hyparhedra edge-hyparhedra (as they involves putting hypars over the edges), and Erik Demain’s original method face-hyparhedra (as it involves putting hypars over the faces of polyhedra).

Whatever it’s called it’s definitely an odd little shape, but I like it!
