I finished the tartan trews this evening so I'll just post about that and then leave all the finishing off for tomorrow. I don't think painting tartan is actually that difficult. Yes, you need a steady hand and a very fine brush, but otherwise it's just a question of keeping one's nerve. It takes time, but I don't think technically it's as difficult as some people think. I think highland socks/hose is way harder to do. Anyway, this is my recipe for government sett, the standard AWI tartan.
Tomorrow I'll do the final highlighting on the black leather and haversacks, add the silver buttons, and generally tidy up. I managed to finish the batch of ACW rebs I'd started on Wednesday - with another 8 figures to go, this will give me one finished unit and a couple of stands of another one.
