I saw a box similar on Pinterest that inspired me to make this pattern. The sides I used 1/2" wood and dadoed them to set the top an bottom into. I have lots of boxes on my FB page.

I used Mahogany, Walnut, and Aspen. Used my scroll saw to make the top pieces. I had to make the pieces pretty accurate for it to come out good. I was afraid to make them on my table saw because they were so small.
