I actually plan to make another one of these in a Christmas setting (to be honest, if I had the time, I would create a whole Christmas village).
The first part is the House ornament base. This a square base that is hollow should you wish to add wiring for some tiny lights (Something I will definitely do next time). I covered mine in white paint, then added some miniature grass which was leftover from a school project. We got this from a hobby store and is designed especially for miniatures.
The main part of the project was the house of course. I started with a basic house ornament, then added the House ornament porch, the House ornament chimney and dormers, the House ornament window trims, and the tiny little shingles on the roof. (Don't worry, these come in strips, they do not need to be glued one at a time). Once assembled, I painted the whole thing with a white base, then sponged a little brown ink onto the roof. The rest I just left white with some flower soft on the window sills like tiny little flower boxes. The final touch was some mica flakes at the front door to look like a cobble walkway.
