Another method I have seen used is just a tad of watered down white wood glue brushe lightly on the crown area.... just enough to penetrate perhaps a half milimeter or so... nothing that you cant easily reshape off. I have also seen celuloid laquer used for this. One later "washes" the laguer deeper into the felt by application of thinner. Would like to hear what you end up doing. "David M.
