Lawrence & Foster, my capmaker of record, is offering several models on its web site at reductions from its already very reasonable prices.
A capmaker is a great asset, for otherwise excess tweed or linen need never go to waste. Half a meter makes one cap and six tenths makes two that will keep a man's head warm, shade his eyes. shed the rain (well, perhaps not the linen), and look good at the same time. And of course, L&F makes caps from their own material as well as that supplied by the customer.
Check them out.
