[sdiy] PCB Etching

[Prototek]

   I gave my first shot at PCB etching using a cheap Radio Shack kit. It
consisted of 2 copper clad boards, etching solution, a marker, and resist
ink remover.
   Instead of using the marker I opted for the transfer stickers. I was able
to transfer them on to the board after a little practice. I then placed the
board in the etching solution for 20 minutes(like instructions said). I
checked it out and there wasn't even a quarter copper faded yet!
   To make a long story short, I let it sit about another 45 minutes and
jiggled the tank around a little. The copper was finally gone, but my traces
were horrible!! Leaving the PCB in the solution that long made my transfer
stickers thinner and brittle, thus allowing the solution to creep through.
   
   Is this how etching with solution always is? What method does everyone
else use.
