I probably goofed by making the crescents smaller than were diagrammed; I didn't want a mammoth jester hat; this is for a little skit and it only has to suggest a jester. So I reduced the measurements a bit...and ended up with a hat that didn't have enough room for the top of The Actor's head.
'Costuming, not couture!'...I opened the seams at the top for about 2", folded the points back and added a hexagonal gusset. Laid the scrap of purple on top of the Actor's head, put the opened up hat on top and just pinned it all to fit; then I zig-zagged around the fold and trimmed all the excess away underneath.
Not at all precise but it worked. I stuffed the crescents lightly w/polyfill...you can see how Very Excited The Actor is with his new hat:
He didn't like the stuffed points at all; after some discussion I let him pull the poly fill out and he was happier. 'Happier' still not meaning pleased, you understand...just less disgusted...
I'm sure I have some jingle bells around somewhere but I've looked everywhere I *think* I should've put 'em and I haven't found them yet. If I find 'em, I'll sew a bell on each point on the hat.
We'll see what The Director says...
