I know there's a few people who have an interest in model railways so hoping you can help. I am wanting to build a castle in 1/12 scale which is fairly straight forward. However, I want to clad the outside in stone block, it's actual structure is MDF. I have some dolls house molds of normal size brick but nothing suitable for castle blocks. I've had a look at these http://hirstarts.mivamerchant.net/mm5/merchant.mvc? And although not in 1/12 I think they'd be ok but I'd have to slim them down otherwise it will weigh a lot!! Has anybody seen anything better I could use? I don't like the textured papers, and anything that can be touched I like to make as real as possible. Even if it was a few blocks I can make my own molds from, but I can't do it from scratch I'm not that clever!
