Homebrew PCBs

I had a go at making my first homebrew board last week, using a 
marker pen, some etchant and a needle. First I set out the design 
using software I borrowed called Easy PC. I printed the pin locations 
on transfer paper and ironed it to the back of the board. Then I put 
the needle into an electric drill, and made the holes. Next I drew 
the tracks onto the copper side, and experimented putting it into 
etchant for different lengths of time, until finally the unwanted 
copper was gone. Then I rinsed and cleaned it. Okay, I think I learnt 
the following:-

1. A needle leaves indentations on both sides of the board. (not good)

2. Life is easier if the holes are far apart.
