I'm making the boiled wool coat, no. 9 of Ottobre 5/2020, from a lovely rich purple-coloured boiled wool. The pattern is for an unlined coat and, when I've been looking through my books for tips on sewing boiled wool, they all say that it is usually made-up unlined.
As all the seams are lapped and edgestitched, the inside of the coat will be neat enough, and in any case the fabric does not fray.
I want to add a lining, firstly for warmth, and secondly because it will be easier to wear and put on and take off. That thing of trying to put your arm into the coat sleeve and ending up with your jumper sleeve pushed halfway up your arm and twisted is just horrible!
My question is, is there any good reason not to line the coat?
