The Day Plaid wrapped and pinned in Victorian era

[Arnot]

I just realised that you are the gent who posted the excellent 'how to' about making your day plaid. I am going to refer a lot to it when I have mine made.
What length of single width tartan do you need to make a plaid that will wrap around and hang well front and back?

I use 3 to 3 1/2 meters of double width.
