This Western-style belt that I wrote about last week came to me too long, so I couldn't get it to fit properly even on the smallest-waist hole.
I pulled out my Ryobi drill driver ($30 at Home Depot and hella powerful for the price), inserted a drill bit that was the same size as the other belt holes, and drilled a new hole an inch tighter:
Now, the belt fits. The hole is ugly, but the belt buckle covers it up when I wear it, so who cares? I didn't have to RMA the belt, reorder, and wait for another one.
