Beginner tips and materials

Hi, I acquired a 1:24 scale doll house.

(Side note: I am aware this sub focuses on 1:12 but > assume many methods and materials are similar enough that it doesn't matter. I'm looking for general information not specific)

Its structure is finished and has been painted but seems like its pervious owner decided to give up at that point.

I'm not really sure where to start to be honest. I have some experiance working with minis but not with whole dollhouses.

I plan on getting some miter shears and I already have a x-acto knife.

Aside from that I planning on siding the exterior wall, putting shingle roof and redoing the floors and baseboards. I not really sure where to quite these materials- I looked online and there are so many websites but I do not know which ones are good.

Any tips would also be appreciated, thanks!
