The Irish Toxic Reef – Call Out

We are exhibiting The Irish Hyperbolic Crochet Coral Reef in The Courthouse Arts Centre Tinahely from September 12th to October 24th. I’m delighted that we will have the opportunity to give our wonderful woolly wonder another whirl. However, we don’t have a Toxic Reef any more, as it was sent of with the Wertheims to be exhibited in it’s entirety at The Smithsonian as they found it to be of an outstanding high quality. This means that we actully don’t have a Toxic Reef to exhibit here any longer, so the call is out for some toxic reef to be produced.


This weekend I’m going to attempt to turn these bags into some toxic coral. Are you going to join me?

If you would like to submit pieces (woolly or toxic), please send to
Irish Reef, Courthouse Arts Centre, Tinahely, Co Wicklow, Ireland

Note: To crochet hyperbolic spheres or planes and be true to the mathematical principals, you just need to increase to the same rate throughout to create a exponential increase. Have fun!

A Dive On The Irish Crochet Corals

Last night we enjoyed the grand opening of the exhibition and everybody that is anybody was at the preview of the Hyperbolic Crochet Coral Reef at Science Gallery Dublin apart from Stitchlily, who was very badly missed. I carried her around on my shoulder all night and I did get the warmest hug from her mother which made the connection that was so badly missing!

I didn’t manage to take many pictures, only a few blurry ones…

The exhibition is magnificent at so many levels and everybody who took part can take pride in it. Every single stitch counts.

I do encourage you to go for a dive into the Science Gallery and submerge yourself in the beauty of maths and fine work by all the fantastic Irish crocheters from all over the country. Take a bow crocheters, you are exhibited alongside two of  Escher’s fine woodcut masterpieces and the masters of Crochet Coral, Margaret and Christine Wertheim. It doesn’t get any bigger than that!

The Science Gallery are to be congratulated on yet another fine visionary exhibition and deserves a great big thank you from all Reef Contributors for letting us in. Dr. Daina Taimina deserves a standing ovation on her findings; I cannot get over the fact that it took a woman with female handicraft skills to crack the hyperbolic code. It blows my mind.
Thanks to Margaret & Christine Wertheim for their generosity in making possible this journey of bringing so many people together and engaging with science in such an accessible way. Although Lynn Scarf at the Science Gallery is the true heroine of this woolly journey, she managed to hold on to all the yarn ends and gave support of gigantic dimensions every stitch of the way! What a woman!!! Thanks to The ReefersTM for the stunning  bouquet
I was presented with which brought a tear to my eye and actually managed to render me speechless. Thank you.
The statistics are that hardly any men have contributed to the crochet reef. I know one man who may not have contributed in crochet but without whom I could not have submerged myself in this woolly wonder, he is my husband. Thank you Dónal for everything.

Irish Hyperbolic Reef – Day 1

Today was the day of Reef Reality. Curators Margaret & Christine Wertheim were at the Science Gallery installing their wonderful exhibition. While they were busy expertly building theirs, we slowly started to find our way with the Irish Reef.

Some of the submissions are fantastic and it is wonderful to see how this group effort consisting of so many different parts slowly becomes a fantastic harmonious whole. Tuesday and Wednesday should see us breaking the back of the installation and Friday is the Preview… Yay!

I Did It Again

Paddy’s Day is coming up. I had to make a bit of ‘Oirish’ Coral… Had to! And here it is:

Note: This coral is worked on hook size 2mm in yarn from unlabelled cone which appears to be flax.


Irish Hyperbolic Update

We had a hoot today playing around with all the fantastic crochet coral that had landed at the Science Gallery. Folks, we have the makings of quite a spectacular reef!


The latest update is as follows:

Submit further pieces of coral to the Science Gallery by Sunday March 7th when the preliminary work of setting up the Irish reef will commence.

Exhibition preview for crocheters on Friday March 19th (details to be confirmed).

Exhibition opening Saturday March 20th (details to be confirmed). The exhibition will run into June. (Exact date to be confirmed)

It will be possible to submit coral to the Irish reef throughout the exhibition. In other words, the reef will continue to grow during the exhibition. YAY!

Little Princess Hyperbolic Coral

I became a very proud grandaunt last week to the sweetest little baby girl, she is pretty, her parents are so happy and her grand parents simply cannot get over the little miracle of life, nor can I. Life really is a miracle!

She obviously inspired me, this little thing, as when I dived into my bag of yarn for Hyperbolic Crochet Coral Reef the other day, I saw the most beautiful heather coloured Cushendale DK yarn and just simply had to make a girly piece of coral. When I found some candyfloss mohair with a delicate gold thread running through it too, I knew exactly what to do. And this is what transpired. A mother and daughter piece that I call Little Princess Hyperbolic Coral.

Hyperbolic Planes, Trains and Automobiles

I am cooped up again today in the snow and the frost as there are no trains or automobiles about at all and the only planes about are hyperbolic. Not that there is much snow, but the combination of snow and untreated icy roads is in and around lethal, so I am staying put. I did try to get some winter tyres for the car, but they can’t be got down here in the bush it seems. Instead, I have taken the opportunity to finish my Fibonacci Rainbow Coral and I have started another one.

I took the photo without arranging the piece, I just left it on the floor and took a picture. The piece will have to be arranged better if it goes to the exhibition but it really is fascinating how the shape drapes itself just right without any intervention.

I have another piece in the pipeline but I have been defeated by the Toxic idea I had. I’ll have to rethink that one, what better way than with the hook in hand?

Details for submission:
According to the Science Gallery website The Exhibition Dates : 25th March – 28th May

Deadline for submitting coral: 20th February 2010

Post your coral,with your name and address to:
Science Gallery,

There was talk of having a list of names of everyone who contributed to the Reef, and also a special opening. So, include your name and address with your coral submission.

Fibonacci Rainbow

These last few days have been as long as a piece of yarn what with no schedule or alarm clocks in the morning. I am having an absolute ball exploring the hyperbolic shapes, I have found out what shapes the different rates of increase give, I have played around with yarn and I still am. It is pure heaven.

Many moons ago during art class I fell in love with the Fibonacci numbers. I had a teacher who was very animated about the numbers and the golden rate and the aesthetics of it. To this day, I have a hard time looking at symmetry, I much prefer asymmetry to that rate.

While I think up some colourful coral to done the Red for Energy Coral I have experimented with a Double Hyperbolic Plane which I have worked as a soft and gentle curving piece and I am currently edging it with a row of small tight planes shaped as Swirly-whirlies. The process is exiting as the Kauni Rainbow yarn does it’s magic. I love that yarn. I love the coarseness and I love the colour and I am exited about this piece.

My toxic piece is being thought out too. I wonder when I am going to have time for ‘substanting’ all my ideas
