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.

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.
