Another Alignment technique -

First establish the ball-target line by standing directly behind the ball. Second, locate an object (eg. tuft of grass or divot mark) about 6 feet away on the ball-target line - red dot, labelled "X". Third, stand alongside the ball, and place the clubhead behind the ball so that the clubface (short blue line) faces point "X". Fourth, make sure that your foot stance line is perpendicular to the clubface, which means that the stance line is parallel to the ball-target line - yellow line. Fifth, make sure that an extension of the stance line (yellow line) points well left of the target (double-headed red arrow) - as viewed when glancing out of the corner of the left eye at the left shoulder. As a rough approximation, the width of the double-headed red arrow at the target should be about 7 feet for every 100 yards of distance.
