Making over a 60s broad-brimmed hat into a cloche Part 2

I'm afraid I haven't made as much progress with this cloche hat as I'd have liked but then eyesight comes first.  And of course, life has a way of throwing in distractions by the handful.
Anyhow here is my progress to date.  Photo 1 is the front view.
I've reblocked the crown and reattached the brim.  Then I cut it down to the shape I wanted and wired the edge. I'm now more than half way around the edge with the grosgrain. This is a very time consuming part as you have to go in and out of each picot. PHEW! 
Here's the back view with the very narrow brim. I've always liked this aspect of 20s cloches as many ordinary hat brims hit the back of my neck which pushes them cockeyed if I tilt my head back.  

I wish the brim had been a little broader to start with so I could have a more graduated curve to the side of the brim but I still really like the overall look.
Photo 3 is the side view where you can see the angle I've had to negotiate around with the grosgrain. 
And lastly a detail of how I've slightly gather up the grosgrain around that angle. 

I'm still tossing up how I'll trim it but I am leaning towards softly draping fabric to cover the join rather than a straight hat band. Suggestions are welcome.
