Janome now has a darning foot ie it looks like an embroidery foot with a spring designed for the 1600 models. It is metal with a ring where the needle goes down through it. I removed the plastic lens inside the ring and this seems to have resolved the problem.
I usually pull my threads to the top so I can see where they are and not getting tangled underneath.
There are several good groups on Yahoo groups which offer support for starting out on quilting
No, you should have gotten some kind of 'hopping foot" or use a darning foot, that appears to move up and down as you sew.
Yes, all threads start and end coming up. If you don't cut a thread, will you are sewing you could run into the threads and stop the machine or tear the fabric. Like a rope across the road, your sewing path needs to be clean, because you can see the bottom of the quilt.
You need to be reading some kind of longarm machine quilting books. Or go to: LongarmChat.com or Sharon Schambers Network
