I just added the first version of my favorite page to wiki, projects. Like many miniaturists, I'm a collector and I have many miniature collections e.g.:
cat figures and stuff
food, especially fish
rubber ducks and Donald Ducks ...
When the collection has grown enough it's time to use them in a themed project. In a normal dollhouse you can't have that many cakes, but in a cafeteria you can. And if you collect paintings you could use them in an atelier. What is your favorite project and what do you collect?
