Thanks Bob ... The way I case is to submerge the leather for a short period of time....with bubbles still leaving the leather, and then place it in an insulated cooler for about 24 hours....If it is ready (returning to normal color and cool to the touch) and I am ready, I will begin stamping.....If not, in either case, I will place it in a zip lock, and then back in the cooler. It will hold the moisture .... In my experience, important to not over wet the leather. I know there are many ways to case, this is just the one that has worked best for me....Don
