Grandma’s easy needle threading trick: All you need is a bottle cap

a thin steel wire;
a bottle stopper;
a pair of scissors (or a cutter);
some glue (optional).
Take the bottle cap and cut off the crown with scissors (or a cutter). Cut a small piece of the steel wire (thin gauge) and make an eyelet. Then insert it into the cap slot you just made with the eye facing outwards.

Thread the needle
Maybe add a little glue to keep everything in place. Then insert the eyelet into the eye of the needle and the sewing thread: done! The needle is threaded in no time. You can store the accessories you receive in your sewing box along with the other tools.
