I have been trying to figure out a way to use the large cones of thread on my sewing machine. I had purchased one of the flimsy plastic ones from JoAnns but was unhappy with it. Then I was looking at the size of the cone spool and thought maybe if I could find a regular spool of thread that would fit into the cone hole then I could put the regular spool of thread inside the cone spool and set it on my sewing machine. I first tried this with a spool that was about half full and it worked just fine. I finished that spool and put on a full spool but haven't done a lot of sewing with the full spool but I think it will work just fine.
I also think that maybe the older singers do not like cone thread as I have had no luck using it on my Singer 15-91 or my 201. I haven't tried it on my FW. But that is OK, because the cone thread works just fine on my brother CS6000i and my new Singer 160th Anniversary machine.
Here is a couple of pictures of my cone thread spool idea on the machine.
