HSF 14: Paisley & Plaid - 1920s Flat Cap

Since I knew that I'd be well and truly occupied with Costume College this weekend, I got a quick and easy item out of the way for the next HSF challenge a few weeks in advance.  Behold, the early 20th century man's flat cap (part the second).

The hat matches the plaid lined Norfolk jacket that I finished for my honey back in January.  The hat I'd originally made was a touch too small and I had inserted the lining inside out (but I'd run out of time to remake it until now).

The original attempt at a flat cap for the 1920s Joker was made out of the plaid gauze flat lined to linen, then lined with polyester lining fabric.  For this one, I went with a more coordinated match to the suit.  

What the item is: man's flat cap
The Challenge: Paisley & Plaid
Fabric: wool/poly suiting, plaid cotton gauze lining, a few scraps of interfacing for the brim.
Pattern: loosely based on whatever tutorials I could find on a cursory google search.
Year: 1920s
Notions: just the thread to hold it all together
How historically accurate is it? I'd give it a 6/10.  The look is there, but it was not based on any particular extant piece.
Hours to complete: 3
First worn: at the KCCG's Friday Night Jazz Dinner
Total cost: I'm calling it zero, since it's assembled with scraps left over from the Joker's Norfolk jacket project. Even then, it's only a few dollars worth or materials.
