JG- a little trick to remember is that if you re-wet a piece after it's been tooled on, the moisture added may lift some of the leather that has been tooled down. If you need to leave a piece unfinished, put it in a plastic bag, and leave it in your refrigerator. The piece will stay moist and seldom needs additional moisture. Don't work wet leather, let it lose some moisture untill it works "just right". try a few pices of scrap to learn the right color to start tooling. RR.
