Well, I use a commercial "whatsthenameofit", and that "thing" enables me
to do both single- or doublesided pcb:s.
In early years, I used to drill two holes for aligning, and aligned the
artworks over those holes. Then I exposed one side at one time ( it did
work with a lot of care) and as a final etched the hole thing. 
I really don´t know of another method.
