How do I create a centerline (vector data) from two parallel polylines (vector data) in QGIS?

For example, if the distances between two parallel lines are 14m, then I want to create a centerline at 7m from both lines.


GRASS has an add-on called v.centerline. Grass add-ons are a bit different to QGIS plugins. To get GRASS add-ons working in QGIS see How do I get grass plugin working in QGIS for Windows? or search this site further for more info as 'how to install QGIS add-pns in QGIS' has been asked here a few times from memory.
