One of the things my girls like best about their dolls is the furniture. They love the small scale versions of what they have best! We were at the bookstore this weekend and I picked up a great book called Making Doll Furniture in Wood: 24 Projects and Plans Perfectly Sized for American Girl and Other 18″ Dolls.
The book is full of very helpful photos as well as a list of tools, terms and techniques at the beginning. There are 24 projects in the book ranging from chairs, tables, beds, dressers and trunks. While I am not a woodworker, my husband can do a lot of these types of things. My daughters are already working on Daddy to get him to build them some new furniture for their dolls.
