As you can clearly see, there are nineteen windows. Because the dollhouse is home-made, the openings do not match the standard 1:12 windows, and it took me a long time to find a solution. I bought a 4-pack when I was visiting a dollhouse shop; unpainted and unglazed. At least I would do something myself. When I was sure I could use them, I ordered the rest from ebay.
Obviously, I began by painting them, which was quite a job. Then I cut panes from transparent file holder and glued them on the inside of the window frame
I started with the removable walls because they were easier to handle First, I fixed the frame on the outside. It covered the opening neatly, but on the inside, the opening was about half a centimeter too small.
I had to saw off half a centimeter of each inner frame bit. In such situations, you bless the inventor of the mitre box.
Just see what a difference it makes!
On the inside, I added window sills for flowers and decorations.
The gable-wall windows were much more difficult to put in, but by then I was a considerably better miniature carpenter and glazier so eventually I managed all the nineteen.
