I have decided to use a modified version of Cherie O'Dowd's ( I think) Chanel-ish technique from Threads to make the jacket. I don't have a lot of time right now, so I used the same pattern from the ruffle jacket as the base. I just won't add a ruffle. I lengthened it to be approximately the same length as the completed ruffle jacket and took in the shoulders a bit.
The technique has you sew the shell and lining together, then bag them out, then quilt the jacket. I might hand quilt it still. She doesn't use any interfacing for support in the jacket at all and I planned to do it like that, but couldn't. I ended up using some cotton in the shoulder areas and down the centre front and some bias in the hem.
