Adding logo anywhere I want

Let’s say I modeled a plane, and I want to add a logo on the plane’s wings. How would i do something like that. I tried unwraping but it always looks like something weird and I don’t know what to do. Anyone Know of a good tutorial that could help with this? Thanks

If you don’t want to paint a full UV map, you can use the deal trick: http://wiki.blender.org/index.php/Manual/Map_Input#Position_a_Decal_on_a_Mesh

Else, you will need to use an Image editor to position the logo on the correct spot on your UV map.

There is also a great video tutorial about DECALING on blender newbies.
