Pre-lockdowns, I used to do in person classes with customers that bought a new Expression or Creative machine & offered up little tips and tricks to get the most out of their machine. One of the things that I show all customers is how to use the needle threader and make it work every time!
The main thing that people do wrong, is that they do not remember to put their needle in the top most position - THIS IS A MUST. Either use your hand wheel to move the needle to the top position or press "Needle Down" button twice and it will return needle to the right position.
I have done a YouTube video on my channel Century House Quilting that shows my trick - CLICK HERE to view the video.
