Baby wearing/carriers group

Does anyone know of a baby wearing group or something like it with a lending library? I am not local, but a friend just had twins and wants to see what carriers would work for her babies without having to buy all of them. I have a lending library as part of a moms group through our library where I live that you pay a membership fee and can rent different carriers, but I couldn’t find anything for the Chattanooga area when I googled.
