Hi, I have this machine. I would say it was a great sewing machine for sewing, even for quilting. But I have not done a Queen or King size quilt so really can't say if it will do one. I do have one complaint against this particular machine though. It will skip stitches going over to many seams connecting together. I was making the pillowcases and when going over the seam where the cuff, the accent piece and main body of the pillowcase meet it would skip a bunch of stitches and then sew normally. But if I flip the pillowcase over and sew in the opposite direction it would take the seam just fine. Maybe just a quirk on my machine. I love the stitches it has on it though and all of the other features.
