I'm no stranger to making stuff out of paper (I do it for a living actually). Generally if I'm doing wargame stuff with paper, it's something I've designed myself. However, I've seen War Artisan's paper ships pop up on TMP a few times, I even downloaded the free 1/900 64 gun ship from his site a while ago but have never got around to making it up.
These kits are small but fairly simple in design (proving the maxim that the best ideas are often the simplest). I toyed with the idea of having a crack at a version of my own but after making up the free kit I have decided that it's unnecessary as these kits are superb.
I've added some paint and washes over the original card illustrations.
I've followed the instructions as closely as possible, the only major deviation is the used of trimmed toothpicks for all the masts and recycled paperclips for the yards etc. I'm also using a nylon coated stainless steel jewellery wire for the rigging.
My bases use crumpled copy paper, glued with PVA to a card base to give a subtle 3D wave effect after painting.
