Putting the designs on the jackets

It's always very difficult to start painting on the jackets. This is the moment of truth. Nothing can go wrong, otherwise
I'll have to throw away a good jeansjacket..... And every time I start with a new portait, I have to keep going, don't stop. Otherwise the paint will be to dry and the colors won't blend nicely. And still I do not know exactly what i'm doing,
when I paint a portrait!!! I hold my breath and there I go, till I finally see and recognize this unknow person on the jacket. Than, after two hours, I can exhale...
