Obviously, step 1 was to label them. I wouldn't have gotten very far without that. So far, I have base coated their skin, fur, and cloaks. Tonight, I'm going to start basing the green on their armor. I'm really getting excited about this, already noticed a lot of differences between the brands.
I am doing a bit of live-tweeting about it, complete with WIP photos, using #paintdebate. It's really an experiment and not a debate, but that seemed catchier (and better yet, was a largely unused hashtag). So if you want to see my most up-to-date progress, you can do it there. I may do another WIP blog post between now and the end.
If all goes well, they should be finished by the end of next week. Afterwards, I'll take some nice photos of each mini, and do a full write up of what I found out. It's been interesting trying to keep track of all these paints, but so far so good! None have mysteriously walked off yet.
