In other words, if the weight of the skin is 15 to 20 kg, salt should be used for 3 to 4 kg. Spreading salt on the skin removes water and bacteria from the skin. Then the skin is folded well. If there is not enough salt, the skin can be preserved for a while with the help of a mixture of salt and water.
  6. You can also store the skin by drying it in the sun. The skin can be dried in the sun by spreading it in the open or hanging it with wire. However, prolonged exposure to the sun often results in poor skin quality. So the salt method is the safest.
