Here is a "How To" to make a turban/headdress. Then, add any type embellishments
You can turn a Plain Jane (above) to a Fabulous Flapper (below) by adding an Era-appropriate outfit (this one was created by a vintage boudoir doll pattern) and a headband.
Because this glass-eyed doll is missing her lashes, the feather headdress compensates and detracts from the loss. Also, I removed her unflattering vintage wig replacement, and thanks to Sue, her crumbling wig is a new mohair replacement. It's important not to put a thick wig on these dolls. It would look obviously replaced. I'll bet you wouldn't have known her wig had been replaced had you not seen her before photo. Plus, the headdress camouflages any hair issues.
Anyway, some easy and Era-appropriate enhancements that will not alter the doll like painting will. And, making a headdress wasn't as difficult as I thought. If I can do it, anyone can do it!
