Of course, you want to make sure that it is on the correct Class M bobbin. Also, as the Q series has a separate motor for its bobbin winder — which allows you to wind the next bobbin while quilting — you may find you don’t need to purchase more pre-wound bobbins (after you have used what you already have).
