Hi Mike and Brian, thanks for all the pictures and comments. I will try some of your suggestions and let you know if i have any success. Seems stamping grained leather is a tough topic.
I will given Texon a buzz. I visited Leffler a couple times, the guys in the front office arent very helpful.
FYI there a place called Auscraft speciality print in Tullamarine that specialises in leather stamping. I might give them a go, happy to pay for a quality job.
