Step 2: Drill
Using the 1" Forsner bit, drill a hole in the main cavity of your gourd. This will be the entrance for your guests. At this point, you can take out a lot of the seeds and dried interior flesh, but make sure to leave a few seeds inside. Legend has it that this attracts birds to nest in the birdhouse.
Also drill a small pilot hole in the remaining stem and put in the eye screw.
