Another method of creating your PCBs at home.
Draw the lines with a permanent waterproof marker. Please note that the final quality of etching depends on the ink used. You should try different brands or types of markers on a small piece before to find the best one. It does not matter if it is black or blue etc. but if you leave the painted plate for over a few minutes the ink becomes too dry and it flakes in the FeCl3. So freshly paint and etch your PCBs.
