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.
@Tong Mao Chrome tanned leather will never hold a crease like vegetable tanned leather can. It is much more heat resistant.
More heat can be applied, however the pigment on the surface will likely begin to melt.
You could try adding some acrylic resolene to the edges and allow it to soak into the fibres. Allow it to dry before creasing and edge painting.
Acrylic is heat mouldable and may allow the crease to hold better. I have not tried this myself however.
