In Sept 2002 issue # 102 Kenneth King had a great article on How to Read (and fix) a Wrinkle.  Does he have a complete book on wrinkles & how to fix?  I am having a terrible time getting the back of a jacket to hang straignt without those diagonal wrinkles at the shoulder area.  I have changed the slope on the shoulder  – helps some but not enough.  Am in the process of using 2 darts in the back neck area as I do have a slightly rounded back.  I picked up this tip from his article.  Thanks Phillips
