Here's the headdress crescent as it is now.
The paint goes off the edges intentionally - I am trying to encase the raw edges. This may or may not work. If it doesn't, hey, I can make another pretty easy.
There is a layer of thin white silk Wonderundered to black cotton. This laminate layer is flat lined to two layers of canvas that contain a wire along both curves and short bits of ever so slightly curved plastic boning (I KNEW I would use that to my advantage) near each end to force the crescent to become slightly concave at either end.
But my artistic skills are pretty low, so I didn't even manage to make each side a mirror image of the other. *sigh*
