How to do frame and panel lids for boxes?

Hey everyone,



I am pretty new to this and have started a lot of my woodworking with boxes to get better with various tools.

I often will make a simple box with a panel inserted into a groove for the lid then saw the lid off as a whole.



I recently saw the thread below - Walnut jewlery box. I did post, but have a feeling the thread is quite old now.



I would love some advice on making frame and panel lids where the panel sits flush with the frame (rather than sitting in a groove below) and furthermore, I was bewildered as to how this boxes lid was made.



I understand the basics like the inlay around the burl veneer. Where I am stumped is: On the outside the " frame" around the panel looks maybe 3cm wide but on the inside pictures the lid shuts as per normal like it was sawn off as one and meets with the box which looks about 1cm thick.



I dont think I would be able to work to that level for many many years (if ever), but would love to know the technique used to do that, if any of you know?



Thanks all
