I didn't have much luck with the clothes iron, just a few boards that weren't pretty, but usable. Finding just the right paper, the right heat setting, right amount of pressure, and how long to iron, are a lot of variables to deal with. Some people swear by the magazine paper and iron, guess it gets easier once you find the magic combination. I found Pulsar paper online, ordered a pack. Later the same day, found an inexpensive 4" laminator (about $20), figured the paper was a little expensive to experiment on with clothes iron, it was worth a shot. Both worked out with no problems, except a little clumsy handling the copper. The paper releases quick and easy,no soaking for 20 minutes, no scrubbing off pulp, board is ready to etch in just a few seconds after the laminator. I only use 2 passes on my boards, one per side.
Some people don't mind doing the extra work, for a board that only costs a few pennies to produce. I prefer to just get the thing done quickly and painlessly. If I could find a cheap CNC drilling machine... Drill press isn't too bad, but after 30-40 holes, I'm wanting an easier solution. Just plain lazy I suppose, but would much rather be soldering.
