Using a piece of string with tees attached to both ends is the best set up and alignment tool you can have, put it in the ground to represent your target line then use it to square your clubface, align your body to the target line and maintain a constant ball position
Open up the club face to increase loft and swing into the lip
Stradeling a string on the ground will help you see immediately if you stay centered throughout your swing or if you are swaying back or forward through the shot which leads to a faulty impact position
