How to help peak of cap stay up on display

[HaerrHistory]

I have this cap that sits flat when sitting on my display shelf. Are there any know remedies to fix this.     First pic is how it sits and second is how I want it to sit.

Have you tried placing it on a mannequin head?

I use old rags/dish towels/etc. (obviously clean) and just shove them up in the visor body to allow it to keep its shape.  Do that on my visors that sit on torso mannequins I use for display as well as shown.  Yes, I am cheap!

Acid free tissue paper works great and I have used it numerous times.  It can be found on-line at archival suppliers like Gaylord Brothers or at your local craft shops.  Just make sure it is acid free and not "regular."  You also never want to use colored tissue paper as it is not acid free and has the distince possibility of bleeding. 
I have also used unbleached muslin bought at the local fabric store.  It is thicker so a little bit harder to work with.

You can use polyester batting, it’s what they use for padding for archival hangers. So it’s non-reactive and gives the thickness you need to perk your hat up.

Crushed tissue paper works, I believe.

Make sure it’s acid free
