When you are seaming sleeves to the shoulders,

How-to Questions
1

Do you start at the middle of the sleeve/top of the shoulder and work down the front, then start again at the middle/top and work down the back, or just start at the front (or back) and work to the front? Or any which way you please?

I do know that it’s best when doing the sides to start from the bottom edge to the armpit and from the cuff to the armpit to hide any problems there.

I start at the shoulder seam and work my way down to the armpit–for the same reason that I work from the cuff up. Any irregularities are hidden.
