Step 2
Wash the leather with glycerin-based saddle soap, using a clean shoe dauber (or your hands).

Step 3
Allow the leather to dry - DO NOT USE HEAT. The leather should feel creamy, but not wet. The flexibility should remain.

Step 4
Dawb the cracked leather with mink oil paste.

Step 5
Using the back side of your spoon, rub the cracks, lightly. This should smooth the oiled leather to the point that the cracks appear far less deep and pronounced.

Step 6
Once the cracks are as minimal as you can get them, treat the entire item with the leather conditioner of your choice. Buff to a gloss.

Step 7
Be certain to treat once a week with conditioner.
