How to correctly make a stencil using paint.net?

[The Something]

I messed around with a the brightness and contrast and got what I think is sorta a stencil. Looked all around the paint.net forums for help and couldn't find any tutorials, also on google. Nothing.





Any help would be greatly appreciated.
