I finally got brave and cut into one of my pieces of boiled wool.
This is the jacket part of my 6-piece-Autumn-Collection, though it may have more than 6 pieces in it.
There isn't actually a centre back panel but I created one by cutting down through the back dart and adding on a seam allowance.
The rest of the skirt will later be cut from some dark navy tweed flecked with a lighter navy and white. This same fabric is planned to also be another jacket from the same pattern and then the skirt can then be worn with either jacket.
There may be extra tweed fabric left, but I suspect it is too nubbly for trousers, so a plain skirt, a waistcoat or even a sleeveless dress?
Anyway for now I am going to be working on the jacket though I am in work all day, have an evening haircut booked tomorrow etc etc so we shall have to see how much I manage to do in the evenings.
