I also have a brother 1500s which i love, love, love, and i am considering buying a speed control for it also in order to keep the speed at a steady pace for free motion quilting. I was just wondering how it works, i understand that you push a button to start and stop the machine, and how does that work when you are sewing and have to lift your hand to push the button. Seems to me it would be awkward. Any advice from an experienced user. thanks.
