Start with a dry belt on a clean surface, and check for damaged holes or sharp buckle projections.
Follow the direction the strap naturally curves around your waist, instead of forcing a sharp reverse bend.
With a small buckle, leave a roomy center so the hardware and pin cannot press into the leather.
For bulky buckles, try starting from the tip and leave the hardware outside the loose finished coil.
Pack the coil beside soft clothing, away from hard corners, and check that luggage will not crush it.
