I have a Janome embroidery machine and have had nothing but trouble with it. Same problem, bird's nest underneath. There was always an excuse when I brought it in when it was under warranty. I asked for a new machine, but dealer refused. I searched on line and found that there are a lot of people having the same trouble with their Janome. I told my dealer what I had found out and he told me that Janome had that problem years and years ago, but it was corrected many years ago. We know that is not true. It seems people either love their Janome or hate it. When I went looking for a new sewing machine, the same dealer was very high on the 6600 and the Horizon, but there was no way I would consider a Janome, even with the great deal she was offering me on a 6600. I went with a big Brother and I am so glad I did.
