I think we all have those DUH moments! I threaded a hand needle about 15 times and it kept coming unthreaded when I pulled the thread through. I discovered that, instead of picking up the thread that I had just cut off of the spool, I was threading it with the little piece I had just taken out of it. DUH! Sr. moment, blond moment, crazy cat lady moment....not sure what was going on that day!
