Reddit reviews Tiny Treasures: Amazing Miniatures You Can Make! (American Girl Library)

This is a book I had as a kid about making tiny things. Loved it.

Seriously, you should get your sister this book for a birthday gift or surprise.

I had it when I was a girl, and it's perfect for creating doll house miniatures easily. I still remember how to make the barbeque using that pizza box tripod, the top of a plastic egg that's been painted black, a circle of screen door screen for the grill, crinkled orange cellophane for coals, a piece of cotton ball for smoke, and lentils for burger buns.

It's an awesome book.
