hi, i have problem with mirror modifier when i make mirror it makes stuck in each other

It mirrors around the objects center (the large pink dot). Move all the vertices to the right of this in edit mode or move the center point itself. Then you can select ‘Do Clipping’ to fix the center line.

The mesh origin (Pink dot) is in the wrong place.
The modifier mirrors around this dot.
You can simply select and move all your vertexes in edit mode, make sure that the origin is on the mirror line - the middle of the face.
a i get it :d
Tried Blender 2.5 yet? 
I’d suggest studying it instead, cause the whole GUI changed.
yes i tried 2.5 and i was confused 
i’d suggest sticking with it.
All the new features in the future are comming for blender 2.5, it’s never going back.
Btw, Labas
