Thank you Faye, Kathy, and sewmuch2learn, for saying you didn't see anything wrong with the cowl and/or encouraging me to continue on.
It is done.
It has a navy exterior of synthetic origin (Kashi, with Maria, 6/14/13) with a black silk/cotton voile lining (Mood, with Mary, MPB Day 2013).
Invisible side zip.
Full report to come.
