Got a fun project in the planning stage, could use some opinions..

[X_Digger]

A couple of weekends ago, my wife and I came across a box of old mailbox doors, with keys.



I think I'm going to make a few piggy banks out of them- give a few to friends, maybe sell a few.

So I got to thinking about small box styles.

Something as simple as this..



or this version with mitered corners..



Maybe even add some decorative splines..





Or thin finger joints..



Thick finger joints..



Maybe even some rounded corners..



Possibly use some different woods for different sides, etc.

I knocked up a prototype out of scrap plywood.



What's your favorite?

eta: I've got some solid walnut wood to use for the sides, and some white oak to use for the splines, if I use this design.
