Very long upholstery needles

[Gymnast]

Do you know of suppliers of very long upholstery needles longer than 0.5 m or 20"?

For some odd experimental project I like to try to use such a needle. It needs to have a needle eye and one sharp point end. I guess, that it needs to be at least 2 mm in diameter and made of a piano-wire kind of steel.

Do you know of suppliers of such long needles in North America and in Europe?

I found this supplier of a 24" needle in Arizona:

What size is a 11 gauge needle?

C.S. Osborne makes some large needles. For example:

STRAIGHT SINGLE ROUND POINT NEEDLE – HEAVY #554.

Lengths are from 6 inch to 24 inch, with varying diameters.

The 25 inch needle is a gauge 11, which is 2.95 mm diameter.

Here’s a website.

“osborneleathertools.com/product/straight-single-round-point-needle-heavy/”

 

Osborne uses the “British Standard Wire Gauge”.

Maybe the upholstery needle supplier you reference does also.

Refer to this Wikipedia article.

“en.wikipedia.org/wiki/Standard_wire_gauge”

Here’s another reference.
