Nay, first of all...I can't use for my Viking machine. And, you know, to begin with I thought "what a great idea". Then my practical side got to thinking...why not just wind two or three bobbins to begin with when I am starting my project (or even just when I sit down to sew)? It really is no advantage to have the extra bobbin winder...I still have to remove my fabric in order to remove my plate and insert my bobbin...so, just what is the advantage? Personally, I'd rather save my money and spend it on fabric or something else that I really do need!
