Using up tartan scraps...How to make a Tie?

[Creag]

If you're running low on fabric you can also make the blade of the tie in the tartan, and the tail in another cloth - since it will be beneath your collar and behind the blade no one will see.

And if the ratio is right, you can tie some knots (trinity and eldridge, for example) with the body of the tie being the tartan and the knot being the contrasting tail.
