I'm a floater! I pin only the back on the take up roller leader. Then I float the batting about 2 - 3 inches from the pin line on the take up roller, then float the top on that. I also attach side leaders to the backing to keep it taut. That and the weight of the backing, batting and top provide plenty of tension until the last row or so. At that time, I attach the remaining backing to the next roller, tighten it up, and finish the quilt.
This method was necessitated by back, neck, shoulder arm and hand pain that happened when I attached all layers of the quilt to the frame rails. It took a couple of quilts to get it to work right, but since then this method has worked very well.
