Thoughts on hat building

Hat pattern worked the third time. Wish I was doing this not sick, it would be far less annoying.
Will make the block flat topped, with a circle of fashion fabric pleated into the band. This circle will smooth the flat top slightly. Not much. But easier to brain than the curve.
Two layers of this cheap buckram I've got, prolly thrown through the machine for a little extra stiffness. Lining for crown, and crown top, but velveteen on base of brim.
Thoughts on steps...
Pattern.
Cut buckram, sew together as flat things for extra strength. Sew into tube.
Cut lining, a little too long at base of crown and top. Sew into tube, place into buckram tube, cut into curve at top and secure over the top of the crown.
Pattern flat top, based on tube I've just made. Two layers of buckram, lining. Cut into the curve, fold edges down over outside of crown, hand stitch. Yes, ugly, but easy to get to, and will be covered later.
Pattern brim. Shouldn't be much more than an inch. Two layers of buckram, reinforced with machine stitching. Add wire to edge by hand. Cut velveteen, machine sew together on outer edge. Encase buckram, trim/cut curve of inner brim. fold up into crown, hand stitch brim and crown together UNDER the lining. Fold lining in and tack down. Anything unsightly can be kept under some grossgrain if necc.
Cut velveteen circle to size, with SA. Press up SA to make life easier later. Place over hat, pleat neatly into waist of hat. Tack pleats down.
Build the cutest of hat bands from beads and stuff. Stitch on so you don't lose it.
Cover it in feathers.

Only issue I can see? Buckram may still be too hard and obvious under the velveteen. Might need a layer of felt too. But I don't want to make the whole thing too heavy, so we shall see.
Wonder if I can get that rounded look with a bit of padding on the flat top? Oh my, did the caffeine just kick in? God I'm awesome. Will test this idea when I'm closer to that point.

Have I got something stupid to line it in?
