  • 2. Stand on it with your heel against the wall.
  • 3. Mark where your longest toe ends (both feet).
  • 4. Measure from the edge of the paper to both marks in centimeters.

Gently brush leather with a soft bristle brush or hand towel to remove loose dirt and debris. Tough stains may require a leather cleaner.
