I have a Janome 6500 and a Singer 201 and I have quilted many King and Queen sized quilts on these machines. Both of these machines have a slightly bigger harp space than some Domestic machines but I had no trouble moving all of that fabric through doing a SID or outline quilting. I also did some FM in some areas of the quilt. It is possible to quilt large sized quilts on your machine. It does take time but it is a lot of material so don't get impatient.
