Although the plain white shields on the Auxiliaries look great, for the legion I needed that little extra something, plain white didn't really look very legionary to me. It would have to be easy and quick to paint, for my legions consist of about 116 figures when finished.
So I came up with a black double laurel leaf design, which actually looks quite detailed when set on to the white of the shield and is simple and quick to paint. The great thing about white shields is that they look fantastic when dirt and mud is dry brushed onto the bottom of them. I will try to get some images up soon. Also, the laurel leaf was a sign of victory....and so these guys had had some luck.
