Hi - I am quilting on a 12-foot frame. I'm not sure what floating means, but I put my back on the backing bar on the front and back. My top is connected to the top bar. I try to load it squarely. I use the red snappers. Then, I channel lock my computer and it stitches a straight line across the backing and batting. I line my top up with that and baste. I think next time, I will try to load it a little unlevel, pulling up more on the right side, and see if that helps. Thanks for your input.
