I did make more matboard moulding from Kris' tutorial (it's in her kitchen cabinets tut http://1inchminisbykris.blogspot.com/2012/01/part-six-kitchen-cabinets-made-from-mat.html) for all the ceilings; it takes extra work with the matboard cutting and the gessoing but it's easier to cut and alot cheaper than wood moulding! I found a plastic bowl in a stash of odds and ends that my mother collected for me and turned it into the kitchen ceiling light fixture.

I guess I got a bit carried away with the bathroom ceiling, but I had all these scraps that I needed to use up on something! Also I got inspired by a piece in Blondie's cute kitchen vignette http://www.greenleafdollhouses.com/forum/index.php?app=gallery&image=97202 and made some hutches for the powderroom from matboard and dowel rods. They are just in dry-fit here, having been gessoed and needing painting.

I had to do something about the porch light because its wire needed to be routed through on the parlor ceiling, so I made a light fixture out of matboard, bead findings, Al tubing and sewing pins, and installed the siding around it:

It is hanging loose right now because the siding needs to be painted before I glue the fixture in place.

Made and installed the bedroom and parlor ceilings, using up more scraps in my paper collection:

Used the matboard moulding and applied some spackle to make it all look neat; I'll do paint touchups after the spackle is good and dry.

A note about the light fixtures: the two vintage-y looking lights in the powderroom and the bedroom were given me by a colleague, who had found them at a yardsale or something (she also gave me the parasol and the pillow in the bedroom); I don't know who manufactured them, but they were table-top lights with large plugs. The shades are plastic; I kept the finish on the one in the bedroom, but I removed the ratty red velvet strip from the other and glued on scrapbook paper for the one in the bathroom. Interesting pieces.

The lightshade in the parlor was another plastic bit from my mother's findings; I'll apply some more paint to it to cover the original pink color.

You can also barely see that I did make another occasional table (http://1inchminisbykris.blogspot.com/search/label/How%20to%20make%20an%20occasional%20table%20from%20mat%20board.) and spraypainted it in a light taupe for the parlor.

Now to figure out what I am doing about the flooring in the parlor and bedroom (stained planks for the former, and I am waffling between white-washed planks and some sort of carpet for the latter), and finish the siding! I have been siding slowly, taping robustly and letting layers dry for hours in order to minimize warping, but I could probably speed it up a bit. And, now that I have installed and routed all the wiring, I can finally clean up the staircases.
