Began with a couple pieces of scrap cherry. This is what's left over when you buy "character" wood because it's cheaper.

I traced my phone on the back of one side, and you can see the downward lines that line up with the speaker on my phone. I wanted the sound to bounce around, which is why I put it on one edge.

Set up the router to the depth of my phone and free handed it. 

Sand down the inside of the phone hole. 

I decided to go ahead and hit the inside of the hole with tung oil before gluing it together. I'm very happy I did this.

Glue it up.

Once it dried, I ran it through the table saw to square it up and knock off the rough edges.

Decided to bevel the edges on my router table.

Now it's time to sand. I did it all by hand. Started with 120, switched to 220, and finished with a quick run of 600 so I could get a glass smooth finish.

Pics don't do it justice, 3coats of tung oil and some paste wax gave it an amazing finish.
