Providence startup company Teespring is moving most of its Rhode Island jobs out of state.  The company that allows customers to design their own t-shirts is moving 70 of their 120 workers to Louisville and San Francisco.  The 70 Providence workers losing their jobs learned the bad news on Tuesday.  The company was founded in 2010 by a pair of Brown University students who set up a web site to sell t-shirts to commemorate the closing of their favorite bar.
