Thank you to Neen of Universe in Miniature. . .! I won one of the book giveaways, and it arrived the other day along with extra goodies: a plate making kit and a $10 Amazon gift certificate (which were completely unnecessary - but I used it to buy better paper scissors as you can see below and some ribbon for a mini project). So thank you Neen!
I am very excited about the Girl Mechanic because it actually has instructions for how to build an elevator in a dollhouse (although not the most explicit instructions - more of a diagram).
So now I am thinking I may try again to build one in my children's dollhouse -- although I may also just use a sailing cleet for them to pull the elevator up to each floor and hold it there. Anyway, it's back on the To Do List :)
