Baltic Birch plywood makes sturdy lightweight roomboxes that can be combined to create baby houses or larger displays. You can find smaller sized pieces of this plywood in craft and model stores where it is sold to make airplanes, or you can substitute regular plywood.
If you make the boxes shallower, and use standard sized picture frames from an art store to front them, you can make boxes for vignettes to hang on the wall.
Roomboxes can be made from Book Board or strong mount card and grouped together in a bookcase to make a display, or a complete dolls house.
This is really a method for building your own custom sized 'shoe box' to house a display. If you don't want to use the box for a room display, make it shallower to use for a vignette, or custom size it to fit your particular miniature scene or vignette.
Bookends can be a good way to display a small collection of related miniatures. This one could be used for either an outdoor or indoor vignette, depending on how you choose to finish it. It is made from MDF (medium density fiberboard).
Acrylic or 'plexiglass' covers can be made or purchased to fit over these small displays. Size your display to fit existing covers from craft stores or plastic suppliers if you do not want to make a custom cover.
This narrow depth dollhouse scale windowbox display has a large window opening for a storefront, as well as an area for a paved display area, patio, or garden. The lid lifts off or can be hinged, and the front fastens to the box through the use of supermagnets, making it easy to access the contents to set up a display.
This display shelf has room for a small interior display as well as an exterior shelf. It is made of gator board which makes it lightweight enough to hang on a wall. The same technique can be used with a number of different finishes to create a variety of building fronts, from beach huts to small store fronts and souvenir shops.
Simple display boxes or shadow boxes can be used to showcase travel or event mementos, or to hold a small collection while you build it further. These boxes can use a background photo from a trip or special day, to draw attention to the items protected in the case. They are also a great way to show off collectible heirlooms while keeping them dust free.
Break away boxes with hinged sides can be built in custom sizes to hold a range of miniatures or a dolls house scene. The boxes have at least one hinged or drop down side, but they can also be made with clear acetate sides to allow a view into a closed box. The drop down sides can be a means of enlarging the scope of the display, or creating a simple scene for a child's play.
Tea cups can be used to create a series of miniature scenes using quarter scale (1:48) printables and railway building pieces. You can find the printables for the front porch scene shown here in the article on Building a Quarter Scale Front Porch Scene in a Tea Cup. Instructions for Landscaping the Tea Cup Front Porch Scene are provided separately.
