I was staring at the pictures they have in the warmaster rulebook. Just some scenery shots of the elves leaving a sea side fortress and a ship with a few of their character models on it. I think it was elves, but maybe empire but I remember a dragon, no matter...It looks like the ship is just carved out of any foam sheets with some really heavy cardstock cut and glued to the sides to look like timbers and then more of those wooden dowel rods for the masts and yards just like the ones shown. Clothe like paper for the sails.
I keep thinking of the warmaster magazine that shows how they built the town buildings, cant remember which magazine it was though....I believe it had a picture of a city scape getting raided on the front, one of those night images with the fake fires all around for street lanterns or as soldiers would use to see in the dark.
