Beautiful work, I have been watching your "tests"
For gosh sakes don't get upset if I suggest the next one not to drill as deep so you can show off more of the "set"
You put in so much effort and a lot is hidden.
Possibly a trough for the pen.
I realize the letter opener is tall which makes taking a picture of the set difficult.
Can you get a shot with the opener in the center and angle the camera to frame the opener from corner to corner diagonally, that would give a larger view of all the pieces.
I can see bu the holder the reflection of the set so I know it has a nice finish that anyone would be proud to display, I would like to see a closer look of the set.
