my biggest fear, is what if the customer hated it...
situation A: they said do what ever design you want and maybe a few colors of thier choice...

situation B: they provided a sample to copy from...

none of want this to happen, but as a painter, im sure it will happen to all of us at some point. i had one that i had painted, and i specifically told the guy exactly what colors to use and if he didnt have them, id send them to him, as his colors wenrt flouresent and more drab...while i was happy with the work he did... the colors were all wrong...
