Most of the "felt" on the market is poly and won't shrink. Neither will wool felt since the meaning of felted wool is "wool shrunk by washing," Felting itself is the process by which wool, poly, cotton, etc. is already shrunk as far as it can be. The wool felt is probably the most expensive of the bunch but I don't know if there is such a thing as silk felt and don't think I WANT to know what that might cost! LOL
