1. Use a paper type that leaves no fibres when separating if from the PCB after laminating.
I have used normal paper that u find in every office around the world. Not very good, because it leaves fibres. Instead I have begun using photopaper specially designed for laser printers. Works very good for me.
2. When u have printed out a design - never touch it with fingers.
3. Find the piece of PCB that u want to use. If it is full of oxi, then use a piece of steelwool (soap-less is prefered) for cleaning it off. After it looks all shiny, clean with a strong cleaner - like aceton or other laqcuer thinner. Alcohol may work too - don't know - I always use aceton.
If u don't do this, it can cause the design to not stick good enough (or not stick at all) to the PCB.
4. Some say that u should preheat the PCB with the clothes-iron before applying the paper to it. It makes the toner stick to the pcb immediatly - in theory that is . So judge yourself wether to preheat or not for ur project .
When etching the boards in FeCl like I do, there are a couple of important ones. Always use gloves. Never spill ANY - I really mean it - ANY of the FeCl! It will stain both your fingers and everything else it hits in a signal yellow color that won't wash off at all. On skin, ok - it will wear off eventually - but on kitchen counter - no, on walls or curtains - no... so no spilling antyhere! .

But a laminator would be far less work, and faster.
PS. I had to read through what I wrote first to check if there was something totally "off" in there, coz I wrote it last night, and I was so tired my eyes crossed... luckily it looks ok :P.
