That is what I do now. I can make some quite complicated quilting with my domestic machine. I do have an embroidery machine that I love because it doesn't sew and I can sew on my old Bernina while embroidering with my Brother. This new Bernina can do much more to embroidery designs that mine can not do. Also, it has hundreds of stitched built in and the embroidery hoop is 3 times the size of mine. One more thing, The neck area is 12 inches (needle to base), when my machine now has 7 inches. When making a big quilt it makes a world of a difference.
I am trying to start my own bussiness quilting and sewing, so maybe some day I can own something so fancy.
