This would be a great table for free motion quilting! The ad says that it will hold "100 lbs. evenly distributed". So the drop down area might not hold much weight. I, too, have a Sapphire 850 and the machine is quite heavy. Is there anyone out there that has this table? Leah Day has one on her site for $124.00 and free shipping but it is not as big as this one. I guess you could add some brackets to hold a heavy machine. But I would be concerned that it wouldn't hold for long.
