Here is the dollhouse I made (and am still working on). I started it 8 years ago, finished most of the outside, and then put it away for 7 years. I was burnt out. But, alas, I recently became re-obsessed with it, and what you see here is a result of that. The whole house measures 11.25 inches tall. I didn't work in any particular common scale, I didn't even realize there were common scales for dollhouses when I started this. But it is close to 1/4 scale (where 1/4 an inch equals 1 foot in real life). It's not completely done yet, there is always room to keep adding, and to keep obsessing.
I'm pretty excited about this latch. I couldn't find anything that I liked at the hardware store, or even online. So, I fashioned my own. The hinge part came from a thrift store, I added on the knob, and the part with the chain and fastener. At times like this, the dremel is your friend. At almost all other times, you'll have a dremel sitting in a closet, and you'll wonder why you ever bought one.
I love the final result of the latch. It becomes a little mini adventure in itself, a fun way to open it before you see the inside.
