I lost some weight and ran out of holes in my leather belt.
I did not have a leather punch handy, so I just drilled the hole.
Step 1: Measure and Mark
First, I measured and marked the place for the new hole, then punched a little hole in place, using a hammer and a wood-screw.
Step 2: Drill the Hole
I used a regular drill bit, placed the drill bit in the hole I punched with the screw, and just drilled through.
