My Tin Lizzie loves Glide thread -- and so do I. I use it almost exclusively on my Janome Horizon, too. In regard to all the good advice you've gotten about the needle, be certain it's inserted properly. If it's in slightly to the side, your machine won't stitch properly. Classes were very helpful to me, and YouTube still is. You'll figure it out -- it just takes time, patience (not always easy) and practice.
