Not exactly what you’re asking for, perhaps, but I’ve used a “backpack cat carrier” for this (basically a black backpack with mesh bits to see/ breathe through). I sometimes wear it on my front, which looks weird to other humans, but the cats tend to seem happier if they can see my face.
I really appreciate you taking the time to show the step-by-step process of the construction. Very well written and informative :)
