Now that you can see how your shoulder slope relates to the pattern you are making, you know where to begin changing your pattern.
Make sure you have looked at both shoulders seperately. There are many factors in our daily lives that can make you A-symmetrical (like carrying babies on one hip, carrying a heavy purse or backpack on one shoulder, how you stand, etc). If the difference in your shoulder slope is more than 1/4" you will want to alter your pattern peices seperately and then label them "left side only, this side up" and "right side only, this side up"
To alter your pattern, take your pattern peice (if you need a left front and a right front make sure you have traced one off so you can alter it seperately) and mark it for an "L" cut. Making the mark on the shoulder just behind the armhole and below the armhole then cut the armhole off. This cut is made so you are not altering your armhole, so the sleeve of the pattern will still fit without a problem.
(This method is the same for kimono patterns as well)
