I use my Brother Innov-is 4000D for free motion quilting, piecing and embroidery. I just have to remove the embroidery unit to sew on it (more comfortably)
I have also made quilt blocks using my embroidery machine, then quilt as you go to put them together, I quilted the blocks as a whole sandwich (top, batting, backing) then did the quilt as you go to put it together, it is now hanging up as my headboard in my spare room.
This is the front of the quilt,

and this is the back, I used white bobbin thread on purpose to get that faded look on the back,
