I've used that method before; it's a bit ugly, but it works - for very 
simple boards, anyway. The way I do it is I print out the layout using 
my good ol' Inkjet, tightly tape the sheet of paper to the board, and 
drill the holes first. Once all the holes are in place, I meticulously 
draw all lines as they appear on the paper, using a set square to 
measure the lengths and angles. Stone-age technology, I know. I really 
should get a laser printer, but I'm a bit shy on lolly - and space near 
my 'puter, for that matter.

The 2-layer boards using through-hole wire jumpers sound promising. I'll 
start redesigning for 2-layer boards, then. :)
