I have worked in the capacity of an artists technical assistance. I am an artist myself but am also good with fabrication. Working for someone who knows what they want and can clearly express it can be rewarding. Less rewarding is working for someone who doesn't. One young artist i worked for asked me to cut a sheet of board to a set of dimensions she was to supply. She got these dimensions wrong at least four times. Worst still was that she seemed to think her ineptitude was charming... laughing at my increasing desperation. I could fill a book with such stories.
