Some other finger joint designs.

One that is of a different sort.
I did not complete the glue up by keeping the 8 sides from reaching their seated positions against the next piece but rather held them away from each other by a half inch or so.
this gives a spacing which travels at a 45 degree angle from the center of the vase.
When a candle is lit inside the light is thrown at these angles in a soft way making a collection on all the walls of rectangular lighted squares appear all around the room.
If your girl loves candle light this one will make a great Xmas gift.
I used Mahogany and butternut.
Careful don't lite the place on fire.
