The best thing I ever did was sit at the 'needle end' of the machine instead of the 'front' of the machine. That way the left hand is 'behind' the machine and the right hand is in 'front' of the machine and neither hand was hitting the inside throat. Clear as mud? How about you move 1/4 the way around your machine to the left, then face your machine. Clear up the picture any? Good luck!
Also, have a full flat surface otherwise your quilt will get caught on the 'corners' and it will mess up the stitching.
