What exactly do you mean by 'drag'? If the needle isn't out of the fabric yet and you try and move it, it will catch. This means that you are moving the fabric too quickly, or running the machine a too low a speed. If it's physically dragging on the machine bed, polishing it or using a super slider may help. And finally, Viking makes a hopping foot. I would see if it is available for your model. There is a special setting you have to use with it and I'm not sure if the Lily has this available.
