Jack,
Turned out reasonably well - I got some black cotton chord - and even though that would not have been my first choice - I was in a bind for time. I needed it done by yesterday and that big 5 inch brim looks very good turned up on two sides. I left the back down, it just adds something different, since almost everyone seems to cock up all three sides. The curator or the Provost Dungeon, where I was yesterday, on seeing the hat was impressed -so it must have gone okay - thanks for asking -
