Behold, my new bucket hat:

Oh and if you were wondering about the amount of fabric needed, I only had a fat quarter of the Lily fabric and wasn't sure I had enough. Turns out you CAN get a hat (or the outside at least) out of a fat quarter IF the pattern is multi-directional. And you trace before you cut!
Edited to add:
It occurred to me that if any of you are going to attempt this pattern, you might like to know the changes I made.
The modifications I made to the sizing of this pattern was to add 1cm to each end of the brim and crown pieces (when I cut the paper shapes out the brim and crown pieces seemed too short for the top circle piece. Equally if your head was a bit smaller than mine, you could make the top circle piece smaller in diameter. My head usually fits a size 59cm hat.
I also made the brim narrower by about 2cm and the crown height shorter – I did this once I had sewn all the pieces together and tried it on for fit. I guess it is about trial and error until you get something that looks ok and fits your noggin!
To assemble the hat I assembled the entire outside and the entire lining, and then sewed them together around the brim edge, right sides together, leaving a gap for turning. I then closed the gap with a line of top stitching on the brim edge.
