Birthday Crafts For a 6 year Old

 Mini dioramas.

This one was a compass. There was a big air bubble inside that messed with its function so I removed the whole business, making it available for this project.

I saved the watch boxes that were in my Dad's collection. This will be a butterfly pop-up, as demonstrated by the white spring in the middle of the photo. 

The beach-in-a-box, made in a former note paper box. I won't include all the steps here. 

This one comes with plasticine a small ladybug and a few ideas.
