I like your cravat/neckstock as well. Any good closeups of how it's tied, or other details? It's a bit hard to make out the white on white in the photo.
Sorry about the delay Matt, we have been out of the country and away from the computer which has the photograph saved on it. I'll post a close up shortly. The cravat is single thickness polly-cotton, 60" long by 5" wide and done with a coachman's knot. The ends are trimmed with Cluny lace so it can be worn in or outside the waistcoat. It's Inside on this occasion as we had been dining!

And thanks all for the positive comments. The "matching" does not look quite so glaring in real life as my wife's tartan is silk, while mine is 16oz wool.
