This hole patch really drives home the point

After accidentally drilling hinge holes on the wrong side of a jewelry box, I wrestled with how to hide the error. The holes were too small to patch using a plug from a typical plug cutter, so instead, I turned to the shop pencil sharpener. By sharpening the tip of a small dowel the same species as I used for the box's construction, gluing the point into the hole, and sawing off the dowel using a flush-cutting hand saw, the unsightly hole virtually disappeared.
