A self threading needle has a small slot cut into the side of the eye, so the thread can be slid in sideways rather than passed through. You hold the thread against the needle and pull down, and it snaps into the eye.
Who it is for. Anyone with reduced vision, a tremor, or simply the ordinary difficulty of threading a small eye in poor light. It is a genuinely useful accessibility item and it is not widely known about.
The trade off. The slot is both a weak point and an opening. The needle is slightly less strong, and with some threads at some speeds the thread can escape back out through the slot. It suits ordinary weight woven fabric at moderate speed, and it is not the needle for heavy work.
Sizes. Usually 80/12 and 90/14, universal point.
What else helps with threading, because this needle is not the only option.
A needle threader, built into most modern machines. Learning to use the one you have often solves the problem completely.
Light. A small task light directed at the needle makes far more difference than most people expect, and it is the cheapest change available.
Contrast. Hold a piece of white card behind the needle when threading dark thread.
Thread condition. Cut the end cleanly at an angle with sharp scissors. A frayed end will not go through anything.
Try the free options first. Light and a clean cut solve most threading difficulty.
Questions people actually ask
Do they work with any thread?
Best with ordinary sewing thread. Very fine or very thick threads either slip out or will not enter the slot.
Are they available for hand sewing too?
Yes, and the same trade off applies — easier threading, a slightly weaker eye.
