What i have done ( inside )
This is a tricky one. I have sewn around the whole thing including the shoulders. Make sure you are evenly spaced and sewn flat across the top of the shoulders. Turn at the bottom opening and then VERY carefully stitch the shoulders together with tiny little stitches. You usually have to sew on both the top and the lining to make them lay flat. It does work and I think it is the only way to make these work, at least it is all I have ever come up with.
