I had a hard time with the lower looper but finally figured it out. Machine sews nicely.

I love my JUKI MO 644DN sooooo much! It runs smooth and is so quiet. It came pre threaded. I tied my own thread to the threads that were already in the machine and voila! I was able to finish my current project. I am now using my beloved serger on a second project and I could not be happier.
