Questions

 I have a lower left shoulder, and I’ve built up the shoulder pad on that side to compensate for the difference.

My question is: If I use this method, do I also need to deepen the armhole, as you would when using the “pick up the shoulder” method?

And if so, how would I need to adjust the sleeve pattern to make sure the sleeve retains the same sleevehead shape and height as the other side?

P.S. Which method would you recommend for correcting a low shoulder: picking up the shoulder or building up the shoulder pad?
