You put the tiny "wiry" thing through the eye of the needle - then when it is through there is a little gap in the "wiry" thing - put your thread in the gap and pull the "wiry" thing until it is through the eye of the needle.
i couldn't work out if you have to put it through first then put thread through and pull it out, or your way wolf - i looked at a youtube vid in the end
The sort of needle threader which I have is a doddle. A plastic device vaguely resembling a small toy ship with two funnels. You put the eye of the needle into one funnel, the thread across the other, and push a little lever which pushes the thread through the eye.
