Pixey, I can’t imagine the DIME Weightless Quilter wouldn’t work with a Janome embroidery sewing machine for QITH.  We might have to set it a little further behind the embroidery unit or a smidgeon more toward the end in the machine to allow room for the hoop motion, but I’ve looked at that stand myself more than once because I think it would work just fine with my 15000.  It would work exactly the same for line quilting as the ad pix show being done on other machines.
