PCB Diy

Ok , anyone made one before. I think dmitri did. What works and what dont. Trace width, hole sizes. Its easy to drill 1mm hole, i've tried, but how about 0,5mm. Lets try to make some standard that works every time. I'd like to try drawing with pen on PCB too, to see how it works. What about conductive pens. Is 600 dpi high enough. Please share your expirience here.
