Hi guys with my leather work becoming the majority of my work and better class clients. I would like to learn about the chemistry side of it about pigments, dyes and finishes of what's in them and how they actually work ect. I've been on 2 training courses one was with Judy herself another was with another company. I will go on more as every trainer has there own way and I believe you can learn something from everyone. I want to really outclass and out knowledge my competition but there is no training on this. My question is., does anyone know of training or links to articles about this?
