I'm really new to this kind of thing and but I'm afraid I'm not so much an aficcionado as an experimenter.
A few years ago, inspired by a handful of Northern European castles, I designed and built a doll house for my daughters to play with their Barbies (Barbies then, MH now). While it's not at all as elaborate as the kits in this forum and parent websites, I've gotten lots of compliments on it.
Ever since I've thought of improvements--maybe modding it with lights, for example, or adding closets and doors. But with all the compliments I've also begun to consider what kind of viability it might have as a kit. But I have no idea where to start my investigation.
I humbly present it here for your consideration. Comments and suggestions are appreciated, as well as thoughts on what a kit for this kind of house would be worth.
