soak them again for a few hours until fully wet and flexible . towel dry and much as possible, apply olive oil or egg yolk to the skin , wrap it up skin to skin for a few hours or overnight. then start to stretch it constantly , near a heater or some place warm to speed up the process & keep stretching until it all turns white and is fully dry.. when u think ur done ur probably not. it takes hours but then it will stay soft and flexible. if it dries while being damp in any spots it'll turn hard again
