I do have a question, How do you choose the scale? Hi edessedesigns!
Well, most people don't just 'come up' with a scale, most miniaturists pick one of the already established scales, as then you can buy things to go in the houses!
I personally like 1:12 scale- this is the most common scale. It originated from the 'old' (if you're in Australia anyway :P) feet and inches measurement system. One inch equals one foot (12 inches). Your 6 inch doll would be a 6 foot tall man in real life.
I chose that scale because I liked the size of it. It felt not too small, and not too big. I could include plenty of details, and accessories were freely available. I still like 1:12 scale.
However, there are quite a few other scales to choose from! 1:24 (half size scale), 1:48 (quarter inch scale) and 1:144, which is the right size for a dollhouse for a dollhouse! I recently made something in 1:48, it was hugely fiddly. I don't think I'll do that again very quickly, because though it has the advantage of taking up less space, I like details, and I don't like feeling like I have to glue everything down or I'll knock it over. I don't like that finality. I'd do it for the occasional room or display, but not for my main hobby.
I would make 1:144, and put it in a dollhouse! I like challenges. One day I might consider using 1:24 scale.
Some people also work in 1:16 and 1:18 scales. 1:10 is popular in Germany (and would make sense for the metric system!). "Playscale" is 1:6, and this is the size for Barbies and Blythe (I believe.)
You could choose any scale you want however, but people tend to go with what has already been created.
Perhaps readers of Fluffybricks could respond with how they chose their scale of choice? Was it to fit with a certain item or doll? You liked the size? You didn't like other sizes? You didn't know anything about it and then stuck with it?
