You should be able to shear llamas for wool

I'm a knitter, and llama yarn is 100% a thing (well, alpaca yarn is more common but still!). So you should be able to get wool from llamas! Sheep will for sure continue to be the main wool source since they are much less expensive to breed, but this would allow you to have a different source of wool, and would be helpful for those in limited worlds where a wandering trader might spawn but not sheep.
