针帽 / a needle cap

针帽

When we say a needle eye is too small, we are actually referring to the fact that it’s too narrow in width. If we take the length of the needle eye to be the diameter of a circle, then the thread will go through the circle easily.
Therefore, we came up with this idea of a needle cap, made from transparent and extra thin silica gel. The diameter of the cap is slightly smaller than that of the needle eye. All we need to do now is put the thread into the needle cap and then thread the needle, which is much easier thanks to the flexibility of the material.
