Can't be specific from a picture, guessing you may need up to 3/4". You can pin the excess cloth in a < shape. 0 at the point of the shoulder and pin across to the neck in graduated increments. This will give you a visual confirmation of the change. You can also press in the change with an iron and then cover the wedge shape with a piece of tape to hold it. Put the tape on the underside of the cloth.
