Writing for About.com Graphics Software, Ian Pullen has a great tutorial (that gets a jumpstart using templates from our About.com Rubberstamping site) on How to Make a Calendar in Inkscape. Don't use Inkscape? Don't fret. The basic instructions are easily adapted to GIMP and other free graphics software.
