The hole is just too small to use a threader in my opinion. Try holding the needle in front of a dark surface so you can see the hole. Do this under a really good light and trim the thread end at a angle and try to thread the needle. Good luck because those things are tiny!
If you have someone that visits or a young quilter friend, (with young eyes) have them thread the whole package of needles onto the thread coming off your quilting thread spool and knot the end. When you are ready to sew, clip off the knot and pull the first needle and thread out with a long tail. Clip the thread and knot the thread coming off the spool again. This keeps the rest of the needles threaded and ready for the next time. You can quilt for a while before running out of threaded needles again.
