This is a wood star corner block used for trim on Americana themed windows and doors. I saw this at the home improvement store and envisioned a cute wooden trinket box.
I cut a board into pieces the same size as the star trim and glued and nailed it together with a brad nail gun.
I spray painted it white and added hinges and a latch from the hardware store.
It would be fun to decorate this trinket box for the holidays.
