This is a nice free guide to painting ECW figures. Although written for 28mm, the techniques are transferable to 15mm and the advice on what colours to use is really useful.

Thanks very much for that Sean. I will use it to help with my TYW project. The section on painting armour will prove very useful when I come to do all those PP cuirassiers that the early TYW armies loved to field.
