I solved all of my bobbin winding problems by buying a Side Winder (I had a coupon for Hancock's, OK?) which winds bobbins for all machines except some of the new high end machines, no muss and no fuss. And fast, and always with the same directions! Now I don't have to remember all of the details for bobbin making for each machine....and I can get right to sewing. Well worth the few $$$ that I paid!
