Removing doubled vertices

Hi! Im working on my first model (and post! - hello!), and somehow I’ve managed to double half of my model or so. Something went wrong with the mirror modifier I think. There’s basicly a copy of my model overlapping my model. How would I go about fixing this? Thanks! :evilgrin:

Select the vertices and W / remove doubles. Look in the toolshelf or F6 to change the threshold value.
If they are two distinct overlapping objects select one vertex and press Ctrl+L to select the connected vertices. Then delete them.

These are only general comments since you haven’t supplied your blend file for anyone to look at

Ah! Thanks, worked like a charm!
