Just completed my Huron/ Canadian war party for Muskets and Tomahawks - great fun to paint for my first 18th century figures. After some debate about basing, I went for 20mm for the troops and 25mm for leaders; I decided to plump for brown bases with a few light tufts and scatter so that they would be ok on both summer and winter terrain (I used a little bit of snow scatter on the photos that you might glimpse on the bases).
Figures and painting guide used were Galloping Major. Hoping to get a game in when this is over!
