I have the 835 Sapphire and it does have the auto pressure foot feature and it's fantastic for applique when you are turning your pieces frequently it lifts just enough to turn. do you any of you have suggestions though on how to do free motion with the heavier weight cotton threads - I am fine with the 35wt coats and clarks but any variances and my thread breaks - I've adjusted tension and tried different type needles and thread in both vertical and horizontal positions and still have breakage.
