Welcome to the club, "Remember son, Information is Knowledge and Knowledge is Power". I call it "Info-poo-ledge" Remember you heard it hear first guys, New Zealand - birth place of new helpful words.

I thought it might be helpful to make a wee list of NZ suppliers which you can add to if you like, or not, if you don't like. I thought I'd get the ball rolling though with a few of my own, so here goes:

Levana Textiles, they have a large range of normal evil fabric and also some organic cotton and merino.

Designer Textiles, I've spent months in the past trying to get samples from them and I know they have organic cotton and merino but what else I'm not sure. Supposedly they are more expensive than Levana.

Certton, organic cotton, these guys have grown a lot in the last five years and they may have a supplier in NZ now.

Corozo, natural buttons, I think the NZ supplier is Arthur N. Rowe Ltd. in Auckland, email: sewing.rowe@xtra.co.nz

Coa ts Industrial NZ,
Coats have a organic cotton sewing thread line called, Eco Verde, other large international companies have organic cotton or recycled polyester ranges,  I'm just waiting on one more response before I decide who to choose. Tracking down the suppliers in this country can sometimes be a nightmare.

Sewing Time NZ, of course, for all those machines you may need to help put it all together.

That's a small start, but remember, don't help anyone if you can help it.

The Charles Parsons Group is a privately owned textiles house supplying customers throughout Australia, New Zealand and the Asia-Pacific region. I'm buying a stud press off of these guys.
