I once used to do badge and logo designs and found them such a hassle I decided to exclusively do caricatures - the only other artwork I do is for me ! Took this job on for a T shirt graphic for a car racing club, thought that should be simple. How wrong was that.
It took ages with lots of changes for the client - THEN - we get to the printer and all the changes to the format for CMYK processes etc.
Lesson re learned !
