A customer and mate hobbyist has kindly shared with me some pictures of his recenty built Dutch fleet, consisting of two large war galleons from Minairons, as well as a smaller 'race-built' fast galleon from Skytrex --all them at 1:600 scale. Here you can see what they look like:
He chose not to use the Dutch flag sets I published, but to paint some of his own instead. Bases are clear plastic rectangles textured by means of a clear silicone layer. Also, he glued a small magnet at bases bottom, for higher safety when carrying them.
