There is a 90 wt. bobbin thread, we don't sell it. It's used rarely. However, there may be a machine or two out there that is calibrated for the 90 wt. bobbin thread only. So check your manual or call your dealer to be sure. I've never been told that 60 wt. did not work on any machine, but since they make 90 wt., you should check it out.
