No Cande, you don't have to be here a long time to get a response. It is my bet that most here have not tried to make a quilted jacket or someone who has just hasn't seen your question yet.
You've probably already googled quilted jacket patterns and if not maybe try that if you like while you wait for someone here. I'll google it also and see if I can come up with something to help you.
Sorry I couldn't be of more help.
