Does anyone have a sewing pattern for a wide necktie?

I think I've found a use for that dark brown corduroy jacket. There's a 1970s costume contest at a convention in three weeks. If I can piece together a hideous crazy-quilt of fabrics before next Friday, I could make a 1970s-style DIY necktie that would probably win it.
