I'm repairing an Aeolian Grand player organ.  The pallet valves were recovered in sponge neoprene, and I'd like to return to the original felt and leather.  I think they originally used a rather firm felt with a thin pouch leather.

I bought a 1/8" thick felt-covered leather from Columbia Organ Leathers, but this has a 1/16" leather glued on a 1/16" layer of felt.  I'm not sure if this is flexible enough.  Any suggestions as to the type of felt that should be used?
