Welcome -- I am not familiar with the Janome 2011, I have the Janome Horizon 7700.
I have made quilts with fleece on one side and cotton on the other. Sometime I spray baste and bind (no batting). Having the cotton on one side stabilizes the fleece so it can be quilted. I have also finished the quilts envelops style, but was not as happy with it since the fleece stretched a bit more.
A lot depends on the size of the quilt -- the bigger the quilt the more likely there could be stretching so the spray basting is the best way to go.
