Query: Very experienced home sewer taking it up a notch.

I am an extremely experienced home sewer. I don't make my own patterns from scratch but I can alter patterns or swap details from one to another. I recently became interested in taking it up a notch by making a well-structured tailored jacket. This is the book that did it for me. I took an ordinary unlined EZ McCalls jacket: added a lining, added interfacing structure to the front chest, upper back and sleeve cap. Put in another piece to get the collar to lie well. Made my own shoulder pads and tacked them in. Bagged the lining: all thanks to this book. Claire Shaeffer is extremely generous with her experience. Diagrams and text were easy for me to follow. There are a lot of books that give you two good tips and page after page of filler: this book is packed tight with great info!
