I do not like this bodice adjustment at all. I agree that it will mess with the shoulder line. I much prefer doing a full bust adjustment.

I have been making darts in this way for many years. It is nice to see the method affirmed on this site.

I agree with lot of the comments already posted. I have several that are "fav of the moment". What I often think of tho is that in the past, when you purchased a machine, every foot you could think of came with it - including the ruffler/gathering foot which I love - you did not have to purchase, and really could not, purchase separate special feet. I think the walking foot was first in that category. Ah, well, I still keep one of those old machines and love how it sews, but you sure cannot beat the features of my new computerized models!
