Finding open edges of a mesh?

Hi there,

I’ve got a low poly model and would like to subsurf it. It has open edges however (edges that only have a face on one of its two sides) which create ugly artifacts. Is there a way to find those “holes” in the topology of a mesh? It’s supposed to be a completely closed object in the end, so I’d like to go through the open edges and create faces there so subsurfs will work correctly. Finding them manually is very cumbersome and time consuming, so I’d appreciate a way for blender to highlight edges that don’t have a face on either side… or maybe even a way to auto close them?

Is there such a thing? Help is much appreciated.

Kind regards
