This had brought up lots of questions from me. My Janome - 18 months old - leaves a lot to be desired - rubbish on block thickness, can't get a long stitch but does have lot a of decorative stitches most of which are no use for quilting
It came with quilt kit so I do have a 1/4 ins foot, stitch in ditch foot, walking foot but not a freemotion foot (not that I think it would cope with such a thing.
Next - I do change needle before each project but does size matter?
I have been pondering an upgrade but it would have to wait until I can talk to people who know what they are talking about if I do it
PS love variegated thread
