While the Saxon army did not reap much success in the Great Northern War, their red uniforms are in my opinion very nice. And I can take some Poles with them, too. Instead of 6mm, though, I have started this project using 1/72 figures I've had around, and ordered two boxes of Russian infantry from nowhere else than Russia. These Zvezda sets are going out of the market so the price was very tempting.
I will base the figures similarly to my Napoleonic project, 16 infantry with 4 figures on a 4x4cm base, and 8 cavalry on 2x4cm single bases, with the probable exception of one or two regiments based individually on 2x2cm squares to be used for skirmishes. I will retain the one inch width of the cavalry for Lasalle to have units of uniform size.
