There are several ways to acquire a dollhouse. Some (since this can be expensive, it's not for everyone) people buy a ready-made and decorated house first and proceed to more adventurous projects later on. Quite a few buy one of the many kits available to build. Some design and make their own house, these range from simple boxes stacked together to works of art. The other options are to buy a house made to your own design (which is expensive!) Some start with simple room settings.
The same principle applies to miniature objects to go inside dollhouses, such as books and clocks, items of furniture, interior decorations, and dolls. Although shop-bought items are generally of a higher quality, they tend to be more expensive. Homemade items are often cheaper and more rewarding to make as almost any material can be used.
1/12th scale dollhouses are available for under £50 for a simple kit but can run much higher for a large, elaborate, or one-of-a-kind house. There are also dozens of miniature trade shows held throughout the year by various miniature organizations and clubs where artisans and dealers display and sell miniatures and often how-to seminars are part of the show features.
