Santa's Sea Cloth

I've been allowed to buy myself a 6' x 4' Blue Sea cloth from Tiny Wargames as a stocking filler, so that it arrives before the holidays and can be wrapped up to go under the tree well in advance of our habitual trip to the French in laws. I've been after one of these for ages as a companion to the Dark Sea cloth that I bought for my nocturnal coastal forces games. This one will be used for my 1/2400th scale pre-dreadnought project and for other naval things that don't need a dark sea surface like my projected Cold War project in 1/3000th scale, but I will probably keep the original 'stormy waters' cloth for my Baltic and North Sea ironclads, as it just seems more appropriate somehow?
