I've been reading a book about the English Civil War that contains several references to "Monmouth Caps" as worn by the common soldier. Apparently they were felted and very warm.
I've just found some information and a pattern. It doesn't tell you about felting, which is easy to do in a washing machine, but causes shrinkage (can't establish how much) so felting such a cap would be a bit hit or miss. I suppose you could always give/sell the ones that don't fit to people with the matching heads.
