Greetings all,

I'm attempting to put together some of the more formal accoutrements that attend a kilt worn in the evening to a ceremonial occasion.
My questions this time center on the so-called 'fly or evening' plaid. To eliminate confusion caused by semantics, what I am referring to is the separate length of tartan typically worn over the shoulder of a doublet or Prince Charlie, fastened with a broach of some kind and either tucked into the belt or left to hang freely over one's back.

J.C. Thompson's fine little book mentions in some detail how to properly 'fringe' such an item, but doesn't actually give dimensions for it.

Any guidance as to size, sewing necessary and/or real-life experience in wearing such an item would be greatly appreciated!
