My experience is: (1) it's really hard to get the layout to transfer from photo paper to pcb evenly. (2) Once you've done that, it's hard to get the photo paper off of the copper. (3) Etching doesn't work evenly unless you have some sort of heater/agitator Additionally, one should mention that while designing your pcb, you might try to use traces NO SMALLER THAN 8mils Ah… this method again…
