Lee Rothrock said [in 220917 MMDigest], "I'm wondering if anyone has
come up with something that isn't nasty to the paper and more durable
than the rubber band to do the job. Does anyone know of any such?"

Check out girls/women's hair bands. These have an elastic center with
a braided fiber outer cover. Small ones are about the right size for
crank organ rolls, and may be suitable for piano rolls.
