I'm having trouble finding it but there was a website where you uploaded a template you draw on to make your own handwriting font. I feel that would have tons of potential if you wanted to make an unreadable font~

I was trying to see if there was one where you didn't have to make an account, but it seems they fell to the wayside. 😅 This one works tho!
I personally use FontForge and import glyphs from SVGs I've drawn in a vector program (like Affinity Designer or Inkscape) to make my fonts or remix them if the font licenses allow. That being said, there's a bit of a learning curve to doing fonts like that compared to something that'll streamline the process like Calligraphr
