I just love the look of a single back vent in a jacket. I also think that the no-vent jacket tends to cup under after having been worn a couple of times–a quite unflattering feature on my figure.
I also like the look of longer-than-fingertip length jackets. Thus my first question: If I add a center back vent to a ventless jacket pattern, is there a perscribed point to place the top of the opening? Say, in relation to the hem or waist?
Part 2–has anyone tried interfacing the back hem up to 6 or more inches to give it more structure, especially after you have been sitting and get up? I’ve considered it, but am too chicken to try it.
