I get rubberized cloth and leathers and some felts from Organ Supply
Industries (OSI) in Erie, Pa.

I am very pleased with quality and fairly pleased with pricing.
Service is excellent; they usually ship same day.  They will provide a
samples card, which really helps in ordering.

I don't know whether they will sell outside the trade.  I may be able
to provide small quantities at a small markup, if not.

  [ OSI's website indicates that you are required to register before
  [ ordering from them, and it rather seems that you must be in the
  [ trade or organ-knowledgeable to do so.
