Strange edges..

Hi All…I am in the process of learning Blender…I am working with a Head Modeling tutorial, but I’m getting strange edges… I’ll attach a screen shot.

Any clue ?

In Edit mode, Select All then press ctrl-N. This will force the normals for all the polygons to face outside. In a model such as yours the inside and outside easy to determine. On a model that doesn’t have in and out so well defined you would have to turn on the Show Normals option select the wrong ones then Flip normals.

Thanks Jestmart…That worked out great…I turned mirroring off and applied CTRL-N.
