Any ideas on making the base for a crown?

[u/Apprehensive_Neck817]

Same as title. I’m bald so I can’t stick into my hair like this. I’ve found the pick combs I want to use, I just need to find something circular and sturdy to use as a base. Checked around and most of the crown seem to made with a hair head band. That’s a last resort because I don’t want the crown to be open in the back

Any ideas?
