I think that shadow boxes are a cool decoration that no one seems to remember anymore. My grandma and mom have many around the house. Perhaps it's because my grandpa loves to build them with scrap wood. I can recall staring at all the small pieces as a child, looking at every detail.
Here's one made of a yardstick that would be so cute as a teacher gift!
Each separating piece of wood is a cut up yard stick, pushed and glued every two inches from top to bottom.
Her next two are a HIS and HER's, which I think would make a cute wedding present. Either way...who doesn't love tiny things!
