I included these...........
knitted from a 1940's pattern in this Murray and Koster book.
The original pattern was knitted in silk, but I used a very soft Patons Dreamtime baby wool. Even so, everyone agreed that they wouldn't fancy wearing them!
The highlight of the show was a mockup of a Battle of Britain RAF operations room with alerts every hour or so when every one sprang into action. Sorry, no pics as they are in my phone and my Bluetooth is refusing to work.
