Hello tombows,
I am using KiCad only for homemade PCBs including exposure, etching, drilling …
Mostly I stay with single sided Layouts and a combination of THT and SMD.
Though KiCad is not made for this it is perfectly suitable.
The needed steps and parameters have already been described by the other people here.
I print PDF to drawing paper using a laserprinter. No Problems so far.
I posted 2 pictures to show that KiCad is real fun at home:
