It can get very expensive decorating a dollhouse but you can save money  on lots of things from DIY stores or shops like the £1 shop. £1 shop sells packs of vinyl floor styles with different designs  these make great flooring for a dolls house. Many DIY stores will let you take a sample of wall paper or sell off very cheep part rolls that have been used for samples find ones with small patterns for decorating dolls houses tester pots  of paint are also good for decorating a dolls house  instead of buying large tins of paint. Here are some rooms  i have decorated using  £1 shop flooring and sample wall paper.
