While waiting for components I was messing around with adding a silkscreen to the component side of the board. After searching the web I found that some folks reported having great success laser printing on Staples "photo basic gloss" inkjet paper (#item# 648181, $20 for 50 8.5"x11"sheets). I mirrored the silkscreen and printed it onto a half sheet of the Staples paper, lined up the printout face down on the top of my board and then used cloths iron to transfer the toner to the board. There is a lot of information about the process here:
