DK - I decide that the quilted veneer that I had covered the box with was just too bland. So as an after thought I decided to add a bit of embellishment using squares of pau shell and gold mother of pearl shell cut from laminated shell sheet!  I've did this before on my wife's jewellery box where a large expanse of bland veneer needed something to lift it.  These were little squares of coloured veneer, again put on as an after thought.
