You will need to get power to your machine one way or another. I have heard of people holding the foot pedal to sew but I think that would become very tiresome on the hands.
You might need to get some sort of handle with an on off/speed control like this

Granted that one won't work with your sewing machine - I am sure there are others out there that will.
If there is a will, there is a way lol.
There is one person that off the top of my head I know would know the answer for you - Mike from the Machine Shop.
He is a whiz with quilting items.

Give him a call and I bet you will have your answer quicker than you imagined. He sells all sorts of things for quilting systems. I got my puck from him (it's an interface for using with the pcq) He is super sweet and has great prices as well.
No, I don't work there - he was just the first person I could think of that knows more about every machine out there than anyone I have ever come across ;)
