This post comes about a week late, but you'll just have to take my word for it that I actually did manage to get my first "month" (really a first effort of 2 months in one go). The deadline was the 15th, and I finished painting at about 11pm that evening. Depending on your perspective, I either barely got there, or planned it perfectly...
The last part of my first month target was a pair of bolt throwers. Actually, this is a lie. It was originally 10 warriors, but by the time I got to them after painting hammerers and thunderers, and with time gradually sliding away, I decided to change my goals. The bolt throwers were always going to be on the list at some point given that I didn't have any painted, and it was a bit more interesting than yet another group of 10 troops. So here we are.
