I have never been good at basing. At first, I didn't know where to start, so I left it to the end. I have also never been good at deciding a model was done so I never was good at spraying them with varnish. Of all my many models, none have varnish. Therefore, none have bases either, because I was leaving that until the end. So now, I am basing, regardless if it is done. In fact, when I do my Tharn Ravagers, I think I will put the basing material down before I prime it!
So I decided to paint the bases I did last night with FA's Burnt Umber, a really dark brown. I think I did a cross between over brushing and bad painting. I wanted to leave the black in the crevasses, so I dipped my flat blade bush in the paint, ran it across the rim of the paint tray, then drug it across the surface. If the paint covered all the black or just hit the high points, I just let it do what it was going to do. It looks ok now, even if it is a little dark for the Jungles of Lusteria. I did this assembly line for 5 Terradon bases, 16 Saurus, 2 Skink Priests, and a Cold One.
