Hello everyone, it's nice to meet so many professionals here. I have a question about edge creasing on soft and elastic leather, for example "Hermes Togo" leather (see the attached picture for demostartion). I can get a clear line by using FN2 or F2 edge creaser, but after few days the line disappeared and the leather returned to its previous status. I try to change the temperature or pressure and get the same result. So does anyone know how to solve this problem? Thank you very much.
