So i came up with this solution
Step 1: Tack it up!
So needed materials:
x Thumbstacks, where x= number of hats you need hanging
Hats, any hat, So far, this only works for fedoras, but let me know about other hats!
Unfortunately, my camera is currently refusing to focus on the tacks in my wall, i shall update asap, until then I will supply you with a stock photo.
