Michael Linton from Geraldine's ''Giant Jersey'' workshop has spent over 25 years recreating the Bayeux Tapestry, depicting the Battle of Hastings which lead to the Norman conquest of England in 1066.
He's done it by making a mosaic using tiny metal off cuts from a very large industrial knitting machine.
The incredible attention to detail and its historical accuracy is such that it is about to travel to the UK as part of the 950th Battle of Hastings celebrations.
Michael and his wife Gillian Linton will be travelling with it, meaning that they'll be shutting up shop in April after over 30 years of supplying knitwear.
He talks to Kathryn Ryan.
Micheal Linton has made a Tri-Alphametic puzzle especially for Nine to Noon that you'll find here. See if you can do it.
The first five people to email firstname.lastname@example.org with the correct answer will win an RNZ tshirt.
There are three stages to a Tri-Alphametic puzzle:
1. You need to work out which letters represent which number. They represent the numbers 0 to 9 and once you work out that e.g. E = 9 then all the E’s in the sums are 9.
2. Once you have worked out all the letters change the long number back into letters to get the message.
3. Take the top number from each set of sums and add them together to get the hidden word.
