While waiting for my yarn to dye, I decided to make a Flemmish style kerchief or cap to go with my as-yet-unsewn kirtle. The general idea of the head covering comes from several pictures, but they pretty much all look like this one from from the Hours of Charles of Angouleme:
The Medieval Tailors Assistant has a pattern for such a cap which is tailed. Sort of a coif with long flaps, rather like lappets, cut on the bias, which one wraps round the head and ties. See http://www.gelfling.dds.nl/tailed%20cap.html for the one remaining website (and some broken links to sites with construction details, le sigh) about this method of making this head covering. This makes no sense to me as it's highly wasteful of fabric, and for nothing more than a do-rag. Besides which, it sort of looks like you can accomplish the same thing with a rectangular cut veil.
So, I found http://www.heatherspages.net/flemish-kerchief.html which shows an alternate way of arranging a Flemish style kerchief and http://lynnehurstinvites.com/edyth/notes/veil.html which gave me another set of instructions and some dimensions for the thing. I set to cutting and hemming (oh how I hates the hemming) and then pinning and flipping and low and behold it worked! Here you see the results:
