Princess Bubble Gum Crown

The main design of this is for the crown to flex like a hair band so it stays put without putting too much stress on the head. Since it flexes it should fit most head circumferences.
The inner surface of the crown curves to put as much surface as possible against the skull and to keep it from sliding down. Since everyone's head is different you may want to put some foam on the inner face if it feels uncomfortable.
The crown gem in the pictures is a hobby store adhesive backed plastic 'gemstone', but you can print and paint the circular gem to look more accurate.
