Windows
For some reason I thought that this dollhouse did not bring interior window trim but it does. This is the Special Edition Kit of this dollhouse model, so your kit may or may not bring the interior trim. There are some interior photos of this dollhouse, that do not show the interior trim.
The windows are assembled, to fit right into the window openings on the front wall of the dollhouse. Once complete, the windows will hide the inside edges of the window openings and for this reason, I did not paint or finish them in any way.
Assembly
These windows are assembled away from the dollhouse. You can paint the parts before or after they are complete but you must have them painted before they are installed onto the dollhouse.
They are extremely simple to put together. The rubber band clamp is actually a very smart way to assemble these windows and the technique could be used on other similar miniature assemblies, so keep it in mind for future builds.
Installation
Once dry, they are ready to be installed. I installed the interior trims first. Then I added the window "glass" pane to the exterior and installed the exterior trim over them. The "glass" is sandwiched between the interior and exterior trims.
The windows snap right into place but if you have difficulty with the fit, sand the window openings or use a craft knife to shave off some of the wood from the inside edges. I only had this issue with the attic window. The rest fit just fine.
Back to the kitchen tin ceiling. I was lucky enough to find silver scrapbook paper with an embossed design that resembles tin. I used it on the kitchen's ceilings.
