Use a measurement that feels most comfortable. If you pull the belt or measuring tape tightly, then you might end up with a belt that feels uncomfortable to wear.
Use a ruler as you’re cutting to make sure the line is absolutely straight.

It’s not necessary to apply olive oil to the back of the belt. Keep in mind that the extra virgin olive oil will darken the leather.
Use a nail to remove beeswax that may get stuck in the holes.
You can also choose to rivet the leather together if you will not be removing the buckle. Just make sure to put the buckle in place first.
