The Janome MC 9500 is meant to be an embroidery machine. Janome has a full line of quilting machines... the MC 9500 isn't one of them!
What did you have in mind when you bought it? I was torn when I bought my Janome... I ended up with the the MC6500... a quilter.
I figure I'll save my pennies and get an embroidery machine when I have grandchildren to do all kinds of cute things for.
If your other Janome is a quilter... use the the embroidery machine when you want to do the fine sewing!
