[quote=vivientans it possible to adjust the feed dog tension? Or is it only specific to the Horizon? I don't think I'm able to adjust my 6260.[/quote]
Sorry, I don't know about the 6260. I know my other, older, machine which is a kenmore (but made by Janome) did not have any way to adjust the tension on the feet, and it always bugged me. I might have used the wrong term, by the way, when I said "feed dog tension". I'm talking about the adjustment that affects how strongly the feet are pushed down onto the fabric.
