Dorothy....you aren't putting the backing in the hoop? With the auto tension I was not using backing at all on the structured hats, on the unstructured I still put a 3" band of backing across the hoop- that way as soon as it starts sewing the hat back is tied down-no more bouncing up and down and less chance of it pulling or skewing around. Putting the backing under the hoop-without being in the 'clamp' isn't going to hold the hat material in place. If it works, it works...but if you still get material moving around or letters aren't straight, clamp the backing with the hat. Roland
