I had been looking for large size crochet hooks for a while (in NZ) but finally had to buy some off ebay. This was my first ever ebay purchase and may have opened up a can of worms but anyway they arrived in the mail quite quickly and are really cool.
The ladies in the local Wool Shop looked at me blankly when I asked about them and even Spotlight had nothing. Trademe was no good and searching NZ crochet suppliers didn't work so it seems that New Zealand crocheters are a bit behind the times - well as far as experimenting with huge hooks goes anyway. Either that or they are buying from overseas like me?
