I have had the Jamone now since Christmas...Love, Love, Love it...I was having some tension issues when FMG'ing on my last quilt which I used very thick backing...I talked to the dealer who also fixing machines and has been in business for over 30 years...anyways...it was not a bobbin or tension issue it was the needle I was using. They have two quilting needles...a 11 and a 14 for thicker material...I came home put on the thicker needle and it worked like a dream...!!!! no more thread shredding and no tension issue...I wish I would have asked him a few months ago...I also just ordered the blue bobbin case for FMQ'ing it was only 30.00 and I have heard great reviews.
