Threading a needle is one of the most frustrating tasks out there. Luckily though, it doesn't have to be with this hack. It turns out there's a really simple and fool-proof method to thread just about any needle. All you need to do is wrap the end of your thread in some tape and push the tape through the hole in the needle. This prevents any tiny fibers from getting caught in the borders of the hole.
You just have to make sure that you fold the tape thin enough to push it through the needle, or else it'll just be too thick to fit through the hole.
