One summer while I was in college I worked at a silk screening plant. We screened panels of cloth that eventually became shirts. We worked the same designs for weeks. One of the stations had a very hot dryer from the ceiling blowing on the inked panels as they came off the line. Every two hours we rotated stations, but it was the same thing day after day.
When I was fortunate to reap the benefit of the twilight saga,I knew I'd have to hunker down and do production work. Even though I designed a few different styles, I was making earrings 40-50 at a time. Soldering and blowing resin bubbles 'til my lungs needed fresh air.
Where's the silver lining you ask? It's the freedom of thought that production work brings. I found myself working new designs in my head while I punched out hundreds of map circles. I'd stop a moment and sketch something in my moleskine. Before I knew it, I had pages of new designs. I probably won't get to them for a few weeks, but just knowing they are there makes me both excited and grateful for all the types of work I do.
